I was able to push up to 800pts in First Avenger with GRRR, baby champ Cap, and Main Event (boosted) before I ran out of health. I decided to pop a 3hr shield, and i'll go back in this afternoon and try to push the rest of the way. I guess it was just She-Hulk that made the other one excessively hard? I find that Main Event is a decent counter to Kitty teams if Grand Entrance is maxed out. As often as not, maybe a little more often than not, it'll blast out 3-4 of the strikes and keep her from being able to boost them, and occasionally it'll actually create a few match-5 cascades such that it actually killed the 3* cap before they even got a turn. I actually kind of enjoy the swap-4 chaos, it plays well with Hell Ride to keep those tiles fresh when they burn to the bottom of the board. I'm considering messing around with a 3/5/5 GR build to see how useful Chain Whip becomes - many times enemies have just quietly killed themselves in the background when i have that out, and that's at 3 covers.
