Bloodblossom Drifter

Death touch
Crystalize (Whenever this deals enough damage to a
creature to kill it, create a token that's a copy of that
creature except it's a green blix enchantment creature
with Crystallize. Then, put a +1/+1 counter on a blix
you control.)
Damage from blix sources can't be prevented.
Whenever a blix you control attacks and isn't
blocked, you draw a card and lose 3 life.
