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.
What decks did you lose to? this list is something similar to something I brewed up to try and fight this FJS meta the polymorph effect with display of knowledge seems pretty good at fighting ambition. Just curious how you your FJS matches played out.
I found that ultimately my cards were not as strong as FJS's despite that the deck itself seemed well suited to go over FJS. As long as the FJS player was able to kill azindel they could usually 1-1 me until I ran out of resources and because of xo and display they would still have some left. The other way I lost to FJS ended up just being out tempo'd. FJS can merch->tomb>vara/removal->rizahn etc and doing anything like that on the play was able to bury me most games.
Pit is bad I think, gift seems alright for a different meta, we are already in trouble a bit vs bore but mask getting bored isnt the end of the world whereas gift getting bored would be. Also the deck kinda struggles on tempo against FJS as it is, I dont think you could find an opportunity to play gift without dying unless you had already won the game.
