Good ideas here. I really like the idea of a Jabba without power combats. My only thought is that with a card that requires your minors to be adjacent, you'd like to see a movement card for the minors to help get them into position. You do have the potential to pull someone next to Jabba, then replace the minors next to Jabba and land 4 damage. But, otherwise, you're tied to the die roll for getting your minors into position. And without an all-roll, you'll almost surely want to move Jabba to keep him away from the opponent.

Rather than Brown, what about Aqua?
