Sure, 99+commander makes sense but why does it fail even when you import the precons? Do I need to something specific to make the commander not count as part of the 99?
Viewing post in Neo Forge: MTG Commander vs AI comments
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!
