uh making generalizing play styles doesn't make it a sufficient counter, if you think it can actually hits and not just win again "people who always sword dance" maybe show calcs about it taking an EQ. Also knock off makes it unable to even revenge.*goes back in time and submits Sneasel*
For real though.
Froakie @ Choice Scarf
Evs: on phone so can't find what they would be, probably 236 Special Attack And Speed, the rest in Attack
Hidden Power Fire
Scarf Froakie in the house! Surf and Ice beam both OHKO an Evioliteless Gligar, and this set is also a great revenge killer in itself. Considering most Gligar players always Swords Dance first thing, you can expect Froakie to get in safe usually.
