I have long grown out of AI5 and onto False Gods but the Gods are of a level where you are expected to lose more than win. AI5 could be that nice dropback where the challenge is good but not overwhelming and you can feel acomplished if you do defeat an AI5. To get this, I think the AI5 card pool needs to be fixed,
At the moment a random 15% will be upped but because of the overlap between Upped and non-upped, its very dificult to get a good spin, often its equivalent of just one card in the deck. Changing this so all cards of the same type are upped would tweak the spins a little bit so when you see blessing come down, they will all be upped and you might get better odds than if only a single card existed. Also, for both AI5 and AI6, let Towers come throught the spins, having to buy the staple card for the same price as as every other card just hurts and its one of the things newer players need to step up.
