Ashiok, Nightmare Muse

Description

Ashiok, Nightmare Muse (THB 256, foil) is a legendary planeswalker that costs {3}{U}{B} from the Theros Beyond Death set. Its +1 creates a 2/3 blue-black Nightmare token that mills opponents when it attacks or blocks, its −3 bounces a nonland permanent and forces that player to exile a card from their hand if able, and its −7 lets you cast up to three face-up cards your opponents own from exile without paying their mana costs. The card provides disruptive graveyard/exile interaction and a potential game-ending cast-from-exile effect that can be used as a finisher or card-advantage engine.
