Mega Mawile is really strong too. It relies on Sucker Punch, so exploit that it only works if you attack and simply set up on it with Swords Dance or whatever, then kill it with faster priority. If you have a faster Pokemon (basicay: anything) with priority, its Sucker Punch will fail and then you can kill it. Or just Will-O-Wisp it and it's instantly worthless.
In other news, Bisharp is still tearing apart offensive teams with Sucker Punch and crippling defensive teams with Knock Off and Defiant. ty based bisharp
I still love making fresh alts on Showdown to singlehandedly 6-0 people with fun things
