I went into Training Mode and found these teleport punishers:
U+3, U+3, U+3, Air Dagger (Far), dash, 2, Dagger Toss (cancel), dash, 2, 3, Red Dash, Red Slide (45%, 9 Hits)
U+3, NJP, dash, U+3, Air Dagger (Far), dash, 2, Red Dash, Down Slash, dash, 2, 3, Red Dash, Red Slide (44%, 9 Hits)
U+3, NJP, dash, B+2, Down Slash, 2, Red Dash, Down Slash, dash, 2, 3, Red Dash, Red Slide (44%, 9 Hits)
U+3, B+2, Down Slash, dash, 2, 3, Red Dash, Up Slash, dash, 2, 3, Red Dash, Red Slide (44%, 9 Hits)
All of these are pretty hard to do except maybe the last two. Helter Skelter's combo in the Post Patch Skarlet Combos thread is also a good one (42%) and easy to do.
