Ganon, Maelstrom Wielder

Trample
Whenever Yidris, Maelstrom Wielder 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.)
