Edit:
Ignore this thread, there is already a general strategy thread.
I’ve been using peacock and valentine mostly, and for those characters I like peackock’s qcf+HK (George at the airshow) becuse it covers a lot of space and trolls jump ins.
As for valentine, I’ve been trying out her qcf+HK (the one where she dashes across the screen) because it can hit at almost full screen, (which is useful for peacock who usually stays out of range.)
