Yidris, Maelstrom Wielder

Mythic

{U}{B}{R}{G}

Legendary Creature — Ogre Wizard

Trample

Whenever Yidris deals combat damage to a player, as you cast spells from your hand this turn, they gain cascade. (When you cast the spell, exile cards from the top of your library until you exile a nonland card that costs less. You may cast it without paying its mana cost. Put the exiled cards on the bottom in a random order.)
