The Grave Digger

Double strike, Haste, Undying.
Whenever a creature is put into a graveyard,
return it to the battlefield under your control. It's
a zombie in addition to its other types.
{b/r}{b/r}: Remove a +1/+1 counter from The
Grave Digger, search your library for a creature
card and put it into your graveyard.
No body goes to waste.
