In Lorwyn's brief evenings, the sun pauses at the horizon long enough for a certain species of violet to bloom with the fragrance of mischief.

Bitterblossom

The effect is mandatory. You’ll lose 1 life even if you have only 1 life left.

The life loss isn’t a payment. You’ll get a token even if you had 0 life (and another effect is stopping you from losing the game).

At the beginning of your upkeep, you lose 1 life and create a 1/1 black Faerie Rogue creature token with flying.

Dark Confidant

If a card in a player's library has {X} in its mana cost, X is considered to be 0.

At the beginning of your upkeep, reveal the top card of your library and put that card into your hand. You lose life equal to its mana value.

Doubling Season

Doubling Season affects permanents that enter the battlefield with a certain number of counters.

If there are two Doubling Seasons on the battlefield, then the number of tokens or counters is four times the original number. If there are three on the battlefield, then the number of tokens or counters is eight times the original number, and so on.

Planeswalkers will enter the battlefield with double the normal number of loyalty counters. However, if you activate an ability whose cost has you put loyalty counters on a planeswalker, the number you put on isn't doubled. This is because those counters are put on as a cost, not as an effect.

If an effect would create one or more tokens under your control, it creates twice that many of those tokens instead.
If an effect would put one or more counters on a permanent you control, it puts twice that many of those counters on that permanent instead.

A grave is the safest place to store ill-gotten treasures.

Entomb

Search your library for a card, put that card into your graveyard, then shuffle.

"I wrecked your metal guy, boss. But look! I made you an ashtray."

Goblin Welder

As the new wording makes clear, both targets must still be legal as the ability resolves in order for it to do anything. If either one or both has become illegal, nothing gets sacrificed and nothing gets returned to the battlefield.

{T}: Choose target artifact a player controls and target artifact card in that player's graveyard. If both targets are still legal as this ability resolves, that player simultaneously sacrifices the artifact and returns the artifact card to the battlefield.

Mana Crypt

No player may choose to take actions between determining the result of the flip and damage being dealt if you lost the flip.

At the beginning of your upkeep, flip a coin. If you lose the flip, Mana Crypt deals 3 damage to you.
{T}: Add {C}{C}.

Sword of Fire and Ice

If the chosen target is an illegal target by the time the triggered ability tries to resolve, the ability won't resolve. You won't draw a card.

Equipped creature gets +2/+2 and has protection from red and from blue.
Whenever equipped creature deals combat damage to a player, Sword of Fire and Ice deals 2 damage to any target and you draw a card.
Equip {2}

Vendilion Clique

Flash
Flying
When Vendilion Clique enters the battlefield, look at target player's hand. You may choose a nonland card from it. If you do, that player reveals the chosen card, puts it on the bottom of their library, then draws a card.
