Choose one — • Destroy all tapped creatures. • Destroy all untapped creatures.

Return target creature card from your graveyard to the battlefield with a finality counter on it. (If a creature with a finality counter on it would die, exile it instead.) Flashback 3WWB (You may cast this card from your graveyard for its flashback cost. Then exile it.)

Vigilance Eerie — Whenever an enchantment you control enters and whenever you fully unlock a Room, put a possession counter on this creature. When this creature dies, create an X/X blue Spirit creature token with flying, where X is the number of counters on this creature.

Destroy target creature or enchantment. You lose 2 life.

Survival — At the beginning of your second main phase, if this creature is tapped, put a flying, lifelink, or +1/+1 counter on it. Whenever this creature or another creature you control dies, if it had counters on it, put those counters on up to one target creature.

As an additional cost to cast this spell, tap two untapped creatures and/or lands you control. Trample

If this card is in your opening hand, you may begin the game with it on the battlefield. You may pay WUBRG rather than pay the mana cost for spells you cast.
