Elum, The Burning Avenger

Trample

When you cast your first instant or sorcery card
each turn exile it with a memory counter instead
of putting it anywhere else.
Illum has +1/+1 for each card exiled with a memory counter.
If Illum's power is 6 or greater, it has menace.

"Oh, you wish to shine above others, let
me help you with that."
