Galea, Kindler of Hope

Galea, Kindler of Hope doesn't change when you can cast Aura and Equipment spells. Normally, this means during your main phase when the stack is empty, although flash may change this.

If the top card of your library changes while you're casting a spell, playing a land, or activating an ability, you can't look at the new top card until you finish doing so. This means that if you cast a spell from the top of your library, you can't look at the next card until you're done paying for that spell.

You can look at the top card of your library whenever you want (with one restriction; see below), even if you don't have priority. This action doesn't use the stack. Knowing what that card is becomes part of the information you have access to, just like you can look at the cards in your hand.

You'll still pay all costs for the spell, including additional costs. You may also pay alternative costs if any are available.

Vigilance
You may look at the top card of your library any time.
You may cast Aura and Equipment spells from the top of your library. When you cast an Equipment spell this way, it gains "When this Equipment enters the battlefield, attach it to target creature you control."

Prosper, Tome-Bound

The Pact Boon ability triggers whenever you play any cards from exile, not just those exiled with the Mystic Arcanum ability.

You must still pay all costs and follow all timing rules for cards played with the Mystic Arcanum ability.

Deathtouch
Mystic Arcanum — At the beginning of your end step, exile the top card of your library. Until the end of your next turn, you may play that card.
Pact Boon — Whenever you play a card from exile, create a Treasure token.

Sefris of the Hidden Ways

A player may only have one dungeon in the command zone at a time.

Choosing the dungeon or room to venture into is part of resolving the venture into the dungeon keyword action. Once that choice is made, players may not respond until after the appropriate room ability has triggered.

Dungeon cards are not part of a player's deck or sideboard. In both constructed and limited formats, players can use any dungeon card when they venture into the dungeon.

Dungeons are removed from the game as a state-based action.

If you somehow venture into the dungeon while a room's ability is on the stack, you will continue on in the dungeon. If you're already in the last room, complete that dungeon and start a new one.

Moving into a dungeon room will cause its room ability to trigger.

Once you resolve the last room ability of a dungeon, that dungeon is now completed and is removed from the game.

Sefris of the Hidden Ways' first ability looks only at the type the card has in the graveyard, not the type it had in any other zone. For example, animated lands dying won't cause the ability to trigger. The opposite is also true. For example, if a creature that was cast as an Adventure is countered, it's a creature card in the graveyard and the first ability will trigger.

The player venturing into the dungeon chooses which dungeon they will venture into. They may choose a dungeon that they have already completed this game.

To venture into the dungeon, a player moves their venture marker into the next room of the dungeon they are currently in. If they aren't currently in a dungeon, that player instead chooses a dungeon card from outside the game, puts it into the command zone, and moves their venture marker onto the first room.

You can only move forward (well, downward) in a dungeon, never backwards or sideways.

Sefris of the Hidden Ways must be on the battlefield for its first ability to trigger. It does not trigger when Sefris goes to the graveyard from the battlefield, even if other creature cards also went to the graveyard at the same time.

Whenever one or more creature cards are put into your graveyard from anywhere, venture into the dungeon. This ability triggers only once each turn. (To venture into the dungeon, enter the first room or advance to the next room.)
Create Undead — Whenever you complete a dungeon, return target creature card from your graveyard to the battlefield.

Vrondiss, Rage of Ancients

Enrage — Whenever Vrondiss, Rage of Ancients is dealt damage, you may create a 5/4 red and green Dragon Spirit creature token with "When this creature deals damage, sacrifice it."
Whenever you roll one or more dice, you may have Vrondiss deal 1 damage to itself.
