Hazre'Mjin Doubledusk

Double strike
Whenever an instant or a sorcery card is put into
your graveyard from anywhere, if it can target
Hazre'Mjin Doubledusk, you may exile it. If you
do, cast a copy of that instant or sorcery spell
targeting Hazre'Mjin Doubledusk.
When a soul enters Agadeem, it is the Crypt that
enters the soul. A pact, which one can't alive resign.
A pact, thus for one - an ascend.
