You should learn this midscreen combo (also works in the corner)
w/e -> 2C 5A 6AA j.C airdash j.A j.C land j.C dj.A j.C j.236B/airthrow (gotta super doublejump and omit 2nd j.A for airthrow)
edit: H-Ryougi can do some cool rekka loops too.
w/e -> 2C 5A 236Ax3 2A 2C 236Ax3 2A 2C 5C j.B j.6B j.C land j.C dj.C j.236B - a bit over 5k on VSion for mad effort. not as good as normal corner combo, but funny and flashy
