i definitely like precursur golem he has a cool effect easily destroyed with disenchant or naturalize or basically all basic artifact destroy. but what i also like is that equipment is equipped as a sorcery so you equipment one with whispersilk cloak and they all get it. or give them all cranial plating first and you basically kill them next turn and they can't do anything about it really but still an easily killed card with a fun effect.

It doesn't have alot of control silence and path to exile can only get you so far i guess theres day of judgement but your other control is pretty costly martial coup and iona need a lot of mana to swing big.

I'd throw in kemba, kha regent or two in this deck just because you can put the lightning greaves on it at the end of every turn and then toss it on any tokens or creatures you throw out on the next phase this way you'll be putting at least one creature out every turn and can focus more on equiping those creatures for maximum damage id put more greaves in there.

i would try bloodchiefs ascension its no creature but it'll up the damage and its a nice turn one pull off with a fast vampire on the next turn. its a nice replacement for your underworld dreams that is a little higher cost with less damage. the underworld dreams would work better against opponents who draw alot plus the bloodchiefs ascension will heal you as well which if you don't kill them fast enough should let you survive in the end.
also gatekeeper of malikir and Vampire Nocturnus would be nice additions.
