Been looking forward to Kat for quite a while, and I think she has more combo potential than anyone could have possibly imagined! This video is more oriented to scoring hard knockdowns and supers, along with some well timed debris links.
Highlights:
Double Debris into forward Circle @ 0:50, run under to up Triangle @ 0:50, midscreen 95AP LV2 combo @ 1:16.
Soundtrack: Moon Trance by Lindsey Stirling.
