So the CM expansion gave me an idea...would it be possible to create a 3 vs 3 scenario where you start with 3 random characters from a pool and every 3 rounds or so, your characters are transformed into other random characters? You'd keep all the cards in your hand, but start drawing from the new character's deck. Could make for some fun battles when your elf wizard sudenly turns into a dwarf warrior! There'd have to be a set number of HP for chars to start with, otherwise starting with all elves would be a big disadvantage. Perhaps it could be themed around a Masquerade Ball...characters switching masks every few rounds? Just a thought!
