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 saw that Isomorphic and LightsOutAce were playing 6-7 merchants in hooru fliers. Instead of changing the number of merchants, I added some cards that make them more effective. I want max copies of most cards and about half as many echo/fate as merchants, which leaves me with this list +/-1 mirror image +/-1 jennev merchant.
