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 would cut pummel. it can only be used in combat, so it can never turn on needlespitter, which is pretty bad. I'd swap that with either main deck signal flares, or a few of the stun+scout card, or just more generic good cards (flame blast, oni ronin, ice bolt)
