You should definitely put Pain Split, which DW Qwilfish got as a tutor move, as a main move in the first set.
Here is how i would make the set:
move 1: Spikes / T-Spikes
move 2: Taunt / Haze
move 3: Pain Split
move 4: Waterfall
T-Wave and Toxic should go to AC, imo, as Pain Split is so much better.
