I don’t have a very well covered Kitty. In fact, mine is 0/1/1. But I HATE fighting her in PVP (when I decide to PVP, I’m much more involved in PVE). I think I’ve only beaten a Gritty team once…maybe twice. But then I pulled a GE Doom Black Cover. Immediately brought him to a fight, had him die on opponent’s 2nd turn, and the rest of the match was a cake walk. It was soooo rewarding.
Try Black Suit Spider-man for the Gritty teams. He passively neuters both Kitty and Grocket.
He technically does not neuter kitty. He does not reduce the effectiveness of her fists or shields. But he dramatically slows gritty.
Learned that the hard way the other day.
