Daemon Warrior

Hellgate 1: 2 Life (You may summon this creature from the graveyard by paying the Hellgate cost but it will be summoned with -1/-1 which cannot be removed)
Every time Daemon Warrior destroys a creature, grant it +1/+1 and every time Daemon Warrior deals damage to a player, grant it +2/+2.
I walk alone on this path of insanity. It feels better than life ever did.
