Here’s a fun game I’ve enjoyed playing in the GSBW PvP.
Pick a team which includes :
GSBW
Mr F
Anyone else
Save up purple and black ap until you have enough to fire gsbw purple once and Mr f black once.
Fire Mr f black
Then use gsbw purple to make as many match 3 as possible and see what your highest damage is.

It’s more fun than it sounds
Who ever expected to have a thread on the forums talking about how fun Mr. Fantastic was to play? 
I’m doing exactly that with 4* Luke Cage as the third. I don’t think I’ve managed to hit 15K yet, though.
Along with your game, you can see how many Imaginaut and Flexibility fortified tiles You can make to use with LC’s Heroes For Hire.
See how many fortified tiles you can keep up by the end of the match. I’ve only gotten as high as ten, I think.
I’ve been doing this as well. They make a surprisingly good pair.
