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.
This deck was pretty good a few weeks ago and is still good. I'm 21/0 with it so far. I will say that I haven't had much use for the Pristine Light in the side. I'm wondering if it might be better to move an Avigrafts to the side and replace them with something else. Or replace the Pristine Light with a 5 - 7 cost unit.
Pristine Light is good against some big decks and when you are really in a bad shape. It used to be a Regent's Tomb, so you can give it a try. Avigraft can shutdown some decks like Grenadin Revolt if you play it on a Grenadin.
