Favorite gimmicky movesets that worked semi-well in competitive,, past generations allowed.

RSE:

Blaziken@Scope Lens
252atk, 252 speed, 4 hp
Focus energy
Blaze Kick
Slash
SkyUppercut

Idea is to hit a critical all the time, didnt quite work consitently but it was definetly fun to see when it worked.

Swampert@Salac Berry
252 Satk, 252 Speed, 4 hp.
Torrent
Endure
Endeavor
Hydro Pump
IceBeam/Blizzard (unfortunatley you need blizzard to get past Zapdos which is the main thing youre trying to counter)

This actually worked wonders. Usually the way it works is you switch into something a regular swampert counters (metagross, ttar, half of the metagame in rse), try to predict the switch, if you predict something that can threaten swampert (hp grass zapdos, most likely, celebi, etc) you actually stay in, hit them with the ice move on the switch, endure their hit, finish them with salac speed boost. If they have a bulky water (suicune, vaporeon, milotic, etc), endeavor them ast hey kill you then finish them later with something fast. If they dont have a bulky water you can literally sweep teams with Torrent Hydro Pump, and its hilarious. Sometimes Suicunes would switch in and try to set up calm mind which is also hilarious because you can get past him and proceed to sweep teams with Hydro Pump
