Laglieth, Abyss Awakened

When you cast this spell, target player exiles cards from the top of their library until they exile a nonland card.

Laglieth's power and toughness are equal to the greatest
mana value among cards in exile.

Whenever Laglieth deals combat damage to a player, draw that many cards, then discard that many cards minus one.

{2}{u}{b}: Exile target card from a player's graveyard. Scry X, where X is its mana value.
