Swain, Noxian Grand General

Whenever you cast a noncreature spell, create a
1/1 black bird creature token with flying and lose
2 life. Then look at the top card of target player's library. You may choose to put it into their
graveyard.
Sacrifice another creature: Swain becomes a
Demon in addition to his other creature types
and gains flying, deathtouch, and lifelink until
end of turn.
