100% agree with the OP. AI5 is useless, I've been doing it a bit to play around with my scarab deck, but realistically its terrible electrum, terrible score, and the decks are stupidly made (they have no cohesive strategy due to the 12x12 format for generating a HB). I'd advocate remaking their decks entirely, and putting them at 50% upped 50% unupped with variations to give them something of a strategy to work with. I'd happily settle for a simple increase in probabilities of an upped card from them too.
