I fixed the list above. I am not sure if I like cranial plating because I will probably lack the BB to move it at insant speed, and it also negatively interacts with arcbound ravager.

I've been playing this deck for a few months casually and have been playing it in tournaments for a few weeks.  Nobody is packing specific hate against it, but I have been able to play around removal spells when trying to build a big ravager.  I tried going on the offensive a little more and played 4 vault skirges. Vault skirge seems to be key in the deck personally because it actually is very well suited in the format. It can't be mistepped because it has a converted mana cost of 2, it has evasion in flying, which is important when building up a big beater with ravager, and it has lifelink which makes racing very easy. Vault skirge having flying also gives the deck a better way to fight grislebrand. I don't know it is more correct to suit up the vault skirge to make it an 8/8 and risk a removal spell, but in racing situations I am able to simply block with the skirge and sac before damage to prevent the life-gain.  I would need someone with more experience in the format to make the decision.

I won my last local tournament with the deck, and before that went 4-0 into top four and lost. There doesn't seem to be any combo decks in my local meta, unless oath is considered combo, so I haven't yet had to deal with just losing on the spot.

I've made some small changes, but because I haven't been playing the deck against a more varied field, I probably ended up making cuts that I should not have made.  I was playing around with the idea of playing some basic islands and splashing master of etherium, but I'm not sure if I have enough sources. The singleton mox opal is because it is part of my 15 cards proxied, but also because chalice on zero has been a killing, so I don't know how much better it would make the deck.

Maindeck:
4 Arcbound Ravager
1 Sol Ring
1 Wasteland
1 Strip Mine
1 Mana Crypt
4 Skullclamp
4 Genesis Chamber
4 Memnite
4 Mishra's Workshop
3 Steel Overseer
4 Signal Pest
4 Vault Skirge
3 Thorn of Amethyst
1 Frogmite
4 Ancient Tomb
2 Gaea's Cradle
1 Tolarian Academy
1 Mox Pearl
1 Mox Opal
1 Mox Jet
1 Mox Emerald
1 Mox Sapphire
1 Mox Ruby
4 Phyrexian Revoker
4 Lodestone Golem

Sideboard:
4 Witchbane Orb
4 Grafdigger's Cage
1 Tangle Wire
1 Thorn of Amethyst
1 Phyrexian Metamorph
1 Wurmcoil Engine
1 Contagion Clasp
1 Pithing Needle
1 Sphere of Resistance

My sideboard right now is just me trying to figure out what I want to do with the deck. I am playing around with contagion clasp for a few reasons. I can cast it off workshop, I can proliferate the +1/+1 counters from both ravager and overseer, its an artifact that I can theoretically tap to tangle wire, and if I have the spare mana, I can just keep tangle wire going.

edit:  was stupid and trying to go from memory, updated to real list.
