My Zimkitty is 4/80 and has 4 talents, and my Mits is 3/70 and rarely sees the battle at all. The only place I use Mits is in events/Atlantis levels when the boss is blue.
Mits’ special kinda works against itself, mana cut prevents the boss from firing, and you’ll need to throw more tiles at the boss to finally trigger the special. But of course, blue special mirroring is VERY satisfying when it finally happens. So, Mits is a very cool, but has the niche that is too narrow.
