Gravekeeper's Commandant

Whenever creature tokens and creatures you control
with Morph are sent to your graveyard, you may
pay 1 life to create a Black 1/1 Zombie creature
token.
You may cast creature cards with Morph from
your graveyard. Their casting cost is equal to their
Morph cost.(Once per turn.)
Whenever a creature enters your battlefield
face-down, or with Morph, gain 1 life.
