Ward—Sacrifice three nonland permanents.

If a card you didn't control would be put into an opponent's graveyard from anywhere, exile it instead.

During your turn, you may play cards exiled with Valgavoth. If you cast a spell this way, pay life equal to its mana value rather than pay its mana cost.

Hexproof

Valgavoth's Lair enters tapped. As it enters, choose a color.

: Add one mana of the chosen color.

Eerie — Whenever an enchantment you control enters and whenever you fully unlock a Room, surveil 2 if this is the first time this ability has resolved this turn. If it's the second time, each opponent discards a card. If it's the third time, put a creature card from a graveyard onto the battlefield under your control.
