Martinex Bone Hauler

Indestructible
Whenever Martinex Bone Hauler enters the battlefield
or attacks, exile a creature from a graveyard. Create a
token that's a copy of that creature, only it's a 1/1
black skeleton with "{b}: Regenerate."
Martinex descended upon high society like a plague.
By the time he moved on, all the graves were empty. As
were all the banks.
