The scarab God can work in this deck if you make it a full on esper deck, and this is why:
metallic mimic can boost your other zombies that you create with
the scarab god. He's an artifact so having him die to a creature such as
defiant salvager on the field will help give you a growing board presence by resurrecting it AS a 4/4 zombie AND by naming zombie you will be giving i other zombies that you bring back from the grave an added +1/+1 counter.
A possible way that I see you running this deck is using
the scarab god to resurrect artifact creatures that you kill off using
defiant salvager and the
herald of anguish. The fodder in this deck could be creatures such as
filigree crawler,
scrap trawler, and
treasure keeper would aid you in a recycling engine where you can turn your robots....in to ZOMBIE BOTS!!! what do you think?
