Yeah, i'll gladly give some more if you don't mind. Gold generation get's a bit absurd quite quick (round 5, you're never running out again), so the only real limitor mid-late game is the amount of slots which are probably filled up with 1 cost, 2 cost junk. So you get pretty odd restraints by the end which will need to be dealt with if the game is extended.
My suggestion is to tone down the gold generation and maybe allow some way of discarding a slot through paying a lot of gold (2 rounds worth). Also, allow the ai to cheat a bit starting maybe round 14, so it doesn't get stuck with the exact same team forever.
But, being honest, it is a fetish game after all so balancing doesn't matter all that much, anyway it's good game, i really like the concept. Also more pics and characters are more important than all the things i listed.
Maybe i shouldn't complain considering im playing it for free
