The problem isn't the indrik's enthusiasm, it's Ravnica's lack of guardrails.

Affectionate Indrik

When Affectionate Indrik enters the battlefield, you may have it fight target creature you don't control. (Each deals damage equal to its power to the other.)

If the target creature is an illegal target when Affectionate Indrik’s ability tries to resolve, the ability doesn’t resolve. If Affectionate Indrik is no longer on the battlefield, the target creature won’t deal or be dealt damage.

You choose the target of the triggered ability as it goes on the stack, but you choose whether the creatures fight as that ability resolves.

When Affectionate Indrik enters, you may have it fight target creature you don't control. (Each deals damage equal to its power to the other.)

Arboretum Elemental

Convoke (Your creatures can help cast this spell. Each creature you tap while casting this spell pays for {1} or one mana of that creature's color.)
Hexproof (This creature can't be the target of spells or abilities your opponents control.)

Because convoke isn't an alternative cost, it can be used in conjunction with alternative costs.

If a creature you control has a mana ability with {T} in the cost, activating that ability while casting a spell with convoke will result in the creature being tapped before you pay the spell's costs. You won't be able to tap it again for convoke. Similarly, if you sacrifice a creature to activate a mana ability while casting a spell with convoke, that creature won't be on the battlefield when you pay the spell's costs, so you won't be able to tap it for convoke.

Tapping a multicolored creature using convoke will pay for {1} or one mana of your choice of any of that creature's colors.

Tapping an untapped creature that's attacking or blocking to convoke a spell won't cause that creature to stop attacking or blocking.

When calculating a spell's total cost, include any alternative costs, additional costs, or anything else that increases or reduces the cost to cast the spell. Convoke applies after the total cost is calculated. Convoke doesn't change a spell's mana cost or mana value.

You can tap any untapped creature you control to convoke a spell, even one you haven't controlled continuously since the beginning of your most recent turn.

Arclight Phoenix

Flying, haste
At the beginning of combat on your turn, if you've cast three or more instant and sorcery spells this turn, return Arclight Phoenix from your graveyard to the battlefield.

Because the beginning of combat step is before attackers are declared, you can attack with Arclight Phoenix during the same combat it returns to the battlefield.

Dimir assassinations are choreographed like dance routines. Each challenge is anticipated and countered with graceful ease.

Artful Takedown

Choose one or both —
• Tap target creature.
• Target creature gets -2/-4 until end of turn.

Artful Takedown’s two modes may each target the same creature, or they may target two different creatures.

A power vacuum for the Azorius. A keepsake for Vraska.

Assassin's Trophy

Destroy target permanent an opponent controls. Its controller may search their library for a basic land card, put it onto the battlefield, then shuffle their library.

If the permanent's controller doesn't search their library, they don't shuffle their library.

If the target permanent is a legal target but isn't destroyed, most likely because it has indestructible, its controller may search their library.

If the target permanent is an illegal target by the time Assassin's Trophy tries to resolve, the spell doesn't resolve. No player searches their library.

Destroy target permanent an opponent controls. Its controller may search their library for a basic land card, put it onto the battlefield, then shuffle.

Assure // Assemble

Create three 2/2 green and white Elf Knight creature tokens with vigilance.

Put a +1/+1 counter on target creature. That creature gains indestructible until end of turn.

When the Erstwhile were unearthed from their tombs, they became a ready-made army for Vraska.

Attendant of Vraska

When Attendant of Vraska dies, if you control a Vraska planeswalker, you gain life equal to Attendant of Vraska's power.

If Attendant of Vraska’s power was negative, you don’t lose or gain life.

If you don’t control a Vraska planeswalker as Attendant of Vraska’s triggered ability resolves, possibly because Vraska left the battlefield at the same time as Attendant of Vraska, you won’t gain life.

The amount of life gained is equal to Attendant of Vraska’s power as it last existed on the battlefield.

Aurelia, Exemplar of Justice

Flying
Mentor (Whenever this creature attacks, put a +1/+1 counter on target attacking creature with lesser power.)
At the beginning of combat on your turn, choose up to one target creature you control. Until end of turn, that creature gets +2/+0, gains trample if it's red, and gains vigilance if it's white.

Aurelia’s last ability resolves before attackers are chosen.

If the creature with mentor leaves the battlefield with mentor on the stack, use its power as that creature last existed on the battlefield to determine whether the target creature has less power.

If the target creature’s power is no longer less than the attacking creature’s power as the ability resolves, mentor doesn’t add a +1/+1 counter. For example, if two 3/3 creatures with mentor attack and both mentor triggers target the same 2/2 creature, the first to resolve puts a +1/+1 counter on it and the second does nothing.

Mentor compares the power of the creature with mentor with that of the target creature at two different times: once as the triggered ability is put onto the stack, and once as the triggered ability resolves. If you wish to raise a creature’s power so its mentor ability can target a bigger creature, the last chance you have to do so is during the beginning of combat step.

Once Aurelia’s last ability has resolved, the creature keeps whatever bonuses it got from that ability even if its colors change.

The target creature gains trample and vigilance if it’s both red and white. It gets +2/+0 only once, even if it’s both red and white, and even if it’s neither red nor white.

"Don't stop till your horns come out their back."

Barging Sergeant

Haste
Mentor (Whenever this creature attacks, put a +1/+1 counter on target attacking creature with lesser power.)

The Dimir rarely make statements, but when they do, the message is clear.

Barrier of Bones

Defender
When Barrier of Bones enters the battlefield, surveil 1. (Look at the top card of your library. You may put that card into your graveyard.)

You perform the actions stated on a card in sequence. For some spells and abilities, you'll surveil last. For others, you'll surveil and then perform other actions.

Defender
When Barrier of Bones enters, surveil 1. (Look at the top card of your library. You may put that card into your graveyard.)

"Bats are welcome to eat thousands of my pets. I have multitudes more that will ultimately eat the bats."
—Izoni

Bartizan Bats

Flying (This creature can't be blocked except by creatures with flying or reach.)

Beacon Bolt

Beacon Bolt deals damage to target creature equal to the total number of instant and sorcery cards you own in exile and in your graveyard.
Jump-start (You may cast this card from your graveyard by discarding a card in addition to paying its other costs. Then exile this card.)

A spell cast using jump-start will always be exiled afterward, whether it resolves, it's countered, or it leaves the stack in some other way.

Beacon Bolt is still on the stack while you count your instant and sorcery cards in your graveyard and in exile. It doesn't count itself.

If a card with jump-start is put into your graveyard during your turn, you'll be able to cast it right away if it's legal to do so, before an opponent can take any actions.

If an effect allows you to pay an alternative cost rather than a spell's mana cost, you may pay that alternative cost when you jump-start a spell. You'll still discard a card as an additional cost to cast it.

If any exiled cards you own are face down, they have no characteristics. If they're normally instants or sorceries, they won't be counted.

You must still follow any timing restrictions and permissions when casting a spell with jump-start, including those based on the card's type. For instance, you can cast a sorcery using jump-start only when you could normally cast a sorcery.

Beamsplitter Mage

Whenever you cast an instant or sorcery spell that targets only Beamsplitter Mage, if you control one or more other creatures that spell could target, choose one of those creatures. Copy that spell. The copy targets the chosen creature.

If Beamsplitter Mage leaves the battlefield or becomes an illegal target for the spell that caused its ability to trigger, that spell is still copied.

If the spell that’s copied has an X whose value was determined as it was cast (like Selective Snare does), the copy has the same value of X.

If the spell that’s copied is modal (that is, it says “Choose one —” or the like), the copy will have the same mode. A different mode cannot be chosen.

If you copy a spell, you control the copy. It will resolve before the original spell does.

If you don’t control another creature the spell could target as Beamsplitter Mage’s triggered ability resolves, you don’t copy that spell.

In some rare cases, the original spell can target another creature but the copy can’t (most likely because an effect modified the characteristics of the original spell on the stack and won’t modify the copy). If the copy can’t target the chosen creature, the copy isn’t created.

The ability triggers whenever you cast an instant or sorcery spell that targets only Beamsplitter Mage and no other object or player, and only if you control another creature that spell could target. If you cast an instant or sorcery spell that has multiple targets and Beamsplitter Mage is chosen as the target in each instance, Beamsplitter Mage’s ability will trigger.

The controller of a copy can’t choose to pay any alternative or additional costs for the copy. However, effects based on any alternative or additional costs that were paid for the original spell are copied as though those same costs were paid for the copy.

The copy is created on the stack, so it’s not cast. Abilities that trigger when a player casts a spell (like Beamsplitter Mage’s ability itself) won’t trigger.

"The tiniest mouse speaks louder to me than all the festival crowds on Tin Street."

Beast Whisperer

Whenever you cast a creature spell, draw a card.

An ability that triggers when a player casts a spell resolves before the spell that caused it to trigger. It resolves even if that spell is countered.

"Watch carefully. The gap between death and victory is thinner than your blade."

Blade Instructor

Mentor (Whenever this creature attacks, put a +1/+1 counter on target attacking creature with lesser power.)

Blood Operative

Lifelink
When Blood Operative enters the battlefield, you may exile target card from a graveyard.
Whenever you surveil, if Blood Operative is in your graveyard, you may pay 3 life. If you do, return Blood Operative to your hand.

If you surveil and put Blood Operative into your graveyard as you do so, its ability triggers once you've finished surveilling.

No player may take actions between the time you choose to pay 3 life and the time you return Blood Operative to your hand.

An ability that triggers "whenever you surveil" triggers after you're done surveilling, even if you have fewer cards in your library than the number of cards you're instructed to surveil. It even triggers if you have no cards in your library.

Bounty of Might

Target creature gets +3/+3 until end of turn.

You may choose the same creature as a target multiple times since Bounty of Might says “target creature” multiple times. You may give three different creatures +3/+3 each, one creature +6/+6 and another creature +3/+3, or a single creature +9/+9.

—Heruj, Selesnya hierophant

Camaraderie

You gain X life and draw X cards, where X is the number of creatures you control. Creatures you control get +1/+1 until end of turn.

The second part of Camaraderie's effect affects only creatures you control at the time it resolves. Creatures you begin to control later in the turn won't get +1/+1.

Selesnya guildmages do not sleep so the rest of the Conclave can.

Candlelight Vigil

Enchant creature
Enchanted creature gets +3/+2 and has vigilance.

Capture Sphere

Flash
Enchant creature
When Capture Sphere enters the battlefield, tap enchanted creature.

Centaur Peacemaker

When Centaur Peacemaker enters the battlefield, each player gains 4 life.

In a Two-Headed Giant game, Centaur Peacemaker’s ability causes each team to gain 8 life.

When Centaur Peacemaker enters, each player gains 4 life.

Chamber Sentry

Chamber Sentry enters the battlefield with a +1/+1 counter on it for each color of mana spent to cast it.
{X}, {T}, Remove X +1/+1 counters from Chamber Sentry: It deals X damage to any target.
{W}{U}{B}{R}{G}: Return Chamber Sentry from your graveyard to your hand.

Colorless mana won’t give Chamber Sentry another +1/+1 counter. Colorless is not a color.

If Chamber Sentry enters the battlefield without being cast, it receives no +1/+1 counters.

If an effect allows you to spend mana as though it were mana of any color to cast Chamber Sentry, you consider only the actual mana spent to determine how many counters it receives.

If another creature enters the battlefield as a copy of Chamber Sentry, consider what mana was spent to cast that creature to determine how many +1/+1 counters it enters with.

The value of X chosen when you activate Chamber Sentry’s first activated ability doesn’t have to be the same value of X that you chose when you cast it.

You can choose any value for X as you cast Chamber Sentry. The value chosen for X doesn’t directly affect the number of +1/+1 counters Chamber Sentry enters the battlefield with, but it does let you pay more mana and thus spend more colors of mana to cast it.

Chamber Sentry enters with a +1/+1 counter on it for each color of mana spent to cast it.
{X}, {T}, Remove X +1/+1 counters from Chamber Sentry: It deals X damage to any target.
{W}{U}{B}{R}{G}: Return Chamber Sentry from your graveyard to your hand.

"It is not your time. The Legion still needs your blade."

Chance for Glory

Creatures you control gain indestructible. Take an extra turn after this one. At the beginning of that turn's end step, you lose the game.

Chance for Glory’s first effect affects only creatures you control at the time it resolves. Creatures you begin to control later in the game won’t gain indestructible.

Creatures you control gain indestructible indefinitely. If you find a way to not lose the game during your next turn, they’ll continue to be indestructible for as long as they remain on the battlefield.

If you somehow skip the extra turn Chance for Glory gives you or skip that turn’s end step, the delayed triggered ability never triggers.

Charnel Troll

Trample
At the beginning of your upkeep, exile a creature card from your graveyard. If you do, put a +1/+1 counter on Charnel Troll. Otherwise, sacrifice it.
{B}{G}, Discard a creature card: Put a +1/+1 counter on Charnel Troll.

Because your upkeep step is after your untap step, your lands will be untapped to help you activate Charnel Troll’s last ability during your upkeep. However, because your upkeep step is before your draw step, you won’t have drawn a card for the turn yet.

You can activate Charnel Troll’s last ability during your upkeep before its triggered ability resolves.

You can’t choose not to exile a creature card from your graveyard if you have one to exile.

"My specialty is theoretical universal limits and ways to circumvent them."

Chemister's Insight

Draw two cards.
Jump-start (You may cast this card from your graveyard by discarding a card in addition to paying its other costs. Then exile this card.)

No guilds—that is her rule. The House vampires unnerve her. The Combine would dissect her, the Legion burn her, the Conclave "cure" her. The shadows are all the family she needs.

By guild tradition, any puddle of multicolored light on the cobblestones can serve as neutral ground.

Chromatic Lantern

Lands you control have "{T}: Add one mana of any color."

Citywatch Sphinx

Flying
When Citywatch Sphinx dies, surveil 2. (Look at the top two cards of your library, then put any number of them into your graveyard and the rest on top of your library in any order.)

When you surveil, you may put all the cards you look at back on top of your library, you may put all of those cards into your graveyard, or you may put some of those cards on top and the rest of them into your graveyard.

"Oh, you fellas are going to love the lockup. Excellent gruel. Very low ceilings."

Conclave Guildmage

{G}, {T}: Creatures you control gain trample until end of turn.
{5}{W}, {T}: Create a 2/2 green and white Elf Knight creature token with vigilance.

Conclave Tribunal

Convoke (Your creatures can help cast this spell. Each creature you tap while casting this spell pays for {1} or one mana of that creature's color.)
When Conclave Tribunal enters the battlefield, exile target nonland permanent an opponent controls until Conclave Tribunal leaves the battlefield.

Auras attached to the exiled permanent will be put into their owners' graveyards. Any Equipment will become unattached and remain on the battlefield. Any counters on the exiled permanent will cease to exist. When the card returns to the battlefield, it will be a new object with no connection to the card that was exiled.

If Conclave Tribunal leaves the battlefield before its triggered ability resolves, the target permanent won't be exiled.

If a token is exiled this way, it will cease to exist and won't return to the battlefield.

Convoke (Your creatures can help cast this spell. Each creature you tap while casting this spell pays for {1} or one mana of that creature's color.)
When Conclave Tribunal enters, exile target nonland permanent an opponent controls until Conclave Tribunal leaves the battlefield.

Connive // Concoct

Surveil 3, then return a creature card from your graveyard to the battlefield.

Connive’s effect lasts indefinitely. It doesn’t wear off during the cleanup step, and it doesn’t expire if the creature’s power becomes greater after Connive has resolved.

No player may take actions between the time you surveil and the time you return a creature card to the battlefield.

The creature card you return with Concoct may be one that you just surveilled into your graveyard.

You perform the actions stated on a card in sequence. For some spells and abilities, you’ll surveil last. For others, you’ll surveil and then perform other actions.

Gain control of target creature with power 2 or less.

"This sort of innovation occurs when you set out to improve an electric tea kettle and misplace a decimal."

Cosmotronic Wave

Cosmotronic Wave deals 1 damage to each creature your opponents control. Creatures your opponents control can't block this turn.

Because Cosmotronic Wave doesn’t change the characteristics of any permanents, the set of creatures affected by its second effect is constantly updated. Creatures that come under an opponent’s control later in the turn can’t block.

Crackling Drake

Flying
Crackling Drake's power is equal to the total number of instant and sorcery cards you own in exile and in your graveyard.

If any exiled cards you own are face down, they have no characteristics. If they’re normally instants or sorceries, they won’t be counted.
