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.
Replaced peaks with quicksilver, removed an ice bolt for an extra xo, Also trying out backlash in the market over royal decree, I do think decree is a better option but I'm seeing a lot of single spell win cons recently.
The deck is designed to purely focus down Hooru and Stonescar decks. Pristine Light doesn't really do anything against either. You could replace the Permafrost though if you wanted. Though i'd probably add in a Feast-Caller before Pristine Light and if i was to add in Pristine Light i'd replace Hailstorm with it not Vision.
