Bitterspire Blixes

Crystallize (Whenever this creature deals
enough combat damage to another creature to
kill it, create a token that's a copy of the creature
except it's a green Blix Construct with
Crystallize. Then, put a +1/+1 counter on a
creature you control.)
Whenever Bitterspire Blixes becomes enchanted, put a +1/+1 counter on a creature you control.
