Okoye / XFDP / Kraven. Unless Kitty has 5 yellow, or the opponent's third is Bishop.
It's what my Wolveroach account uses in simulator when hunting 70+ point matches.
I'm in 4* land and I can beat this team with 3*. I find that it takes careful match to reduce the strike tiles to 3 or fewer.
I don't think the teams that I used to use are helpful because our MMR seems to be different. Champed R4G/Medusa/Gamora/Carnage etc levels that I see in Simulator are between 270 to 300.For Kitty, it's between 255 to 360. The number of covers that I see for her can be between 1 to 13. My mmr is not high enough to meet low level champed Kitty.
