Step 0 Wish Good Fortune for everybody, because you are likely going to need a little luck to pull this off.
Step 1 Do the maths to balance your sigil abacus towards FTTJJSSS. Good luck.
Step 2 Stall out the board with Sandstorm Titan, Steward of the Past, or Statuary Maiden.
Step 3 Set the Clock by bringing Light the Fuse, Black Iron Manacles, and Stronghold's Visage online
Step 4 Get out the popcorn and watch the opponent draw themself to death
The ShiftstonedEternal Power Calculator is a deck-building tool that visualizes your odds of drawing enough Influence and Power based specifically on the cards found in your deck.
So, I've been playing this deck a bit and I think that adding slays instead of vanquish is a good, as well I took out the light the fuses for 2 additional statuary maidens and 2 leave a witness and that has been working pretty well for me. but its your deck so do whatever you want. :)
Those are great suggestions and I have 4 slays and a singleton leave a witness in my post Omens list. More Maidens is definitely a good call. I just have to wonder, if you aren't playing light the fuse, why are you playing this deck? I had an opponent channel the tempest my face, then hit me with a full scouting party and West Wind Herald to channel a second time. He killed himself from full health.
