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.
It's early, in testing, but today, I'm 2-0 with this version and 2-1 with the Jennev version in Gold 2. That's after I went 2-5 with the Hojan/Sharpshooter Rakano deck that's supposedly so good.
