Musharna could be a possibility, as very few pokes can reliably OHKO supereffectively and 2HKO non-supereffectively. Plus it can be a guessing game between signal beam/hp ground/ heal bell, which can be annoying to determine. Its real slow and can be slowed down by sheer offense. Sawk is perfectly fine, plus, there would be almost no fighting types in the tier (gurdurr, throh, scraggy). Sawk can be pretty easily revenged killed.
