What is a good hazards setter for singles (Champions Reg M-B)?

Question

I may get back into singles, so I would like to know what a good hazards setter is.

Also for some reason I can’t find the reg M-B tag despite having used it.

Uh, Skarmory gets stealth rock, spikes, tailwind and can heal using roost. Hippodown with sand and stealth rock. Maybe Forrtress
