I recently maxed G. Chameleon, who I think is one of the best, and most underrated support heroes in the game (he and Tarlak have maybe the best synergy of any two heroes besides G. Jackal and Joon/Poseidon. They make tiles murder engines). I’ve gotten pretty handy at using the color change to my best advantage, and want to see how that interacts with the Norns special ability. I can see a team of Norns/Tarlak/Alby/G. Camelon/(other green/yellow dependent on opponent) being really fun.
There’s more detail here.
