Musharna is the biggest counter, not Misdreavus. Musharna can actually OHKO Sawk (after SR, that is) and has much more reliable recovery. Not only that, but it takes much less damage as well.
The checks and counters section needs a lot more depth. Add everything in the checks and counters section that is said in
this post. Sawk is an incredibly dangerous Pokemon in the NU meta; the checks and counters section needs to be very in-depth.
Mention Fling in Other Options to do a lot of damage to Misdreavus, Duosion, and Musharna. Mention Reversal in AC of Scarf, and Toxic in AC of Band.
Why did you mention Inner Focus in OO if it "sucks dick"? I understand that OO is the place for more gimmicky stuff, but things in OO should at least have
some use.
Your mention of Mold Breaker in Unreleased is a bit off. It doesn't really make Sawk unwallable; it just allows it to break through Weezing. Mention that Mold Breaker gives Choice Band Sawk the niche of OHKO'ing pretty much every single Stealth Rock user. However, giving up Sturdy is not worth it unless you really need to get rid of Sturdy Stealth Rock users and you'd like to bypass Weezing. Being able to EQ Haunter and Missy (you still don't beat Missy if it's not weakened) rather than Stone Edge is kind of nice too.
