Gecko Moria, Shadow Master

Shadow cut - Whenever a creature dies you may
pay {u}{b}. If you do, exile that creature. Then you
may put a creature from your graveyard into the battlefield and it becomes a copy of the exiled
creature except it retains its power and toughness
and is a zonbie in addition to its other types.
Shadow's Asgard - At the beginning of your upkeep
you may pay {b}{b} and put all creatures exiled with
Moria into their owners graveyards. If you do put
that many +1/+1 on Moria.
