Tekka, Grim Dollmaker

Whenever another nontoken creature dies, exile
it and create a token copy of it that is a black
Doll artifact creature in addition to its other
colors and types.
Whenever a Doll dies, return each creature exiled
by Tekka with the same name as the Doll to their
owner's graveyard.
Artifact creatures you control get +1/+1.
