I don't really like that set that much. It's sorta gimmicky.
I'd try something like Brave Bird/Air Slash + Toxic + Roost + U-turn
Toxic + Roost lets you Toxic stall, and even if they switch you get free healing. U-turn gets you out of tight spots. Brave Bird gets you maximum damage, and Air Slash gets you flinch hax (which is really annoying)
