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.
I'd still be wary of playing this as Xumucan does not stack up well against Tasbu, but if you wanted to play this I would suggest the following changes:
-4 Intrepid Longhorn
-2 Conflagrate
-1 Ancient Lore
-1 Fire Sigil
+4 Edict of Grodov
+3 Edict of Kodosh
+1 Kairos' Choice
Market:
-1 Talir
+1 Token of Instinct
A controlling build would be better in Grodov, pre-PBF release at least, but I love playing the Ambush 7/7 so I'm sticking with this. T Edict is best suited for all of the Shadow decks and can still be a good tool against Hooru or with the new Jetis that will most likely start creeping into the meta.
EDIT: For anyone wanting more thoughts on this deck, please check out loPmeei4je8 where I've posted my current list. Feels very solid in my current meta as 75% of my matches have been against some deck with Shadow.
