The invalid cards are nowhere to be found when editing the decks. Is it because of alchemy versions of cards or something? I’m sure could look it up but I’m really more looking to complain about how this is dumb than solve it and try to play again.
For what it's worth, I am looking to solve this. If you could take a screenshot of one or more of the affected decks and add it to this post, and optimally an export of the decklists as well, that would help us figure out what state you're in that isn't clearly displaying itself.
