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 has been great, thanks for this! I only have 1 Aniyah so far, and filled the rest in with Jotun Feast-Caller, which seems to work ok. I think Aniyah would work better in the long run. Feast-Caller's card draw is awesome at times, but you often can't attack with him so it ends up not being useful. Pledge is great at times on Aniyah (especially since you can't 3x mulligan in Gauntlet), and Mirroring her can totally bring you back from the brink.
