Ashiok, Nightmare Weaver

Description

Ashiok, Nightmare Weaver (PIO-352) is a Legendary Planeswalker in Pioneer Masters that costs {1}{U}{B} and has three loyalty abilities. Its +2 ability exiles the top three cards of a single opponent's library and its −X lets you return an exiled creature card with mana value X to the battlefield under your control as a Nightmare, while the −10 exiles all cards from opponents' hands and graveyards. The card is mythic rare, color-identified as blue and black, and carries rulings clarifying how the exile pool and X values interact if Ashiok leaves and re-enters the battlefield.
