Engine Unity (Faction-less)

Prism Golem and Tempting Offer are the stars of this deck, if you can play them early. I've had two 7/7s on board by turn 3, which is so fun!

Otherwise, you're looking to get as many Engines as you can on board before playing Mask Maker and Unity Within.

Momentum Builder can get big fast if you can get him a +1 attack from MM or UW.

Draw/Scout with Family Charter, Petition (for Tempting Offer), Seek Answers, and Replicator Engine.

Warp in Seal of Devotion whenever possible. Hold Sealed Writ as long as possible (unless you need the power). Hope for a late game Broken Contract.

Wasteland Broker usually grabs Caiphus, Wandering King, but has some other outs against certain decks.

This is a meme deck, but I was still winning about 30-40% of the time in Silver/Gold Throne. It's extremely satisfying.

NOTE: For those wondering, I have tested the Vows. If the deck doesn't contain the required sigil, you won't gain influence, nor take the 1 damage. You will gain 1 power only.
