^^ the two decks I used, I played green and the ai was red. Still getting the hang of this game but with over like 50k cards in the library and endless combos it's so deep. The AI is quite smart on Forge too. I've never played MTG in my life so this is all new to me.
It's great! Sometimes it can result in some really annoying and frustrating games. There are some cards that are just broken and can result in some games that are really toxic for other players, but that isn't that often, and really only happens if you're playing with someone who is kind of an asshole anyway.
