I'm thinking of..

[Greg54js]

A mono black legendary creature that can take opponents creatures, make them zombies and put 'em under your control..

Anyone got a name for said legendary?

Yep those are all gonna be part of the deck

[Gorzo]

{Geth, lord of the vault}

They don't come back as zombies, but he's a zombie and might go well with your theme

[Wally]

{sheoldred, whispering one} will also fit with the synergy of all these things.
