Overall, it seems to run well.
However, I am not sure if I am setting up the commander decks wrong or if it's bugged. If you edit one of the preconstructed decks and save, it complains that the deck cannot have more than 99 cards. Commander should have 100 cards and I think the 99 is assuming the commander is not counted.
I have to take out a card for it to be playable.
Also it would be nice if when you select the deck for the AI commander that it actually updates the UI to show the deck name but not a huge deal.

You found a real bug! Depending on how a decklist is written (Moxfield, Arena, commander on the first line...), Forge’s list reader could either move a second card into the command zone or count the commander twice, and that’s the “no more than 99 cards” you saw. It’s fixed for the next update: imported precons come out as 99 + commander. Deck lists will also show 100 cards for a Commander deck, and on Android the deck builder says “99 + commander” like on PC. And the AI deck you pick now shows up under the Opponents button. Thanks again!
