Cosmic LOL is pretty good. I have him too but only on 3 purple stars at the moment but will be upgraded to 4 later today I hope. Still to get a final talisman set up for him as he is pretty soft - at the moment I think I had Avenger and Dominance on him.....but as other shave said he can take anything which was the main reason I got him to be honest. Still a bit annoyed at the devs for making him gunner for upgrades - that makes zero sense. I had thought it would be the clear ones for him, but alas not!
