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.
Really sad what happened to you in the ECQ, but I am SO excited that you are on here posting decks again. The first deck I ever hit masters with and still my favorite deck in the history of eternal (that sadly doesnt hold up that well in the current meta) is your old M&N Green list.
UPDATE: Knifebloom (rank 1 player) used this deck with a 100% WINRATE over the course of a very large sample size (1 game).
