I don't know it this isn't common, but why not try.
Jynx @ Life Orb/Leftovers
Trait: Dry Skin
EVs: 252 SpA / 4 Spd / 252 Spe
- Substitute
- Lovely Kiss
- Ice Beam
- Psyshock/Psychic
I run LO but Leftovers is a less suicidal approach. This moveset allows Jynx to cripple counters and prevent Revenge Killing thanks to LK and Substitute, respectively. After putting someone to sleep, put a Substitute and hit the switch in hard while it tries to break the Sub. If the opponent stays in you can kill it while preserving the Sub, meanimng you have another chance to LK again. This set is walled by common defensive walls that wall all non-NP Jynx sets but works well against offensive teams who rely on Revenge Killing to take out Jynx.
