important to note, though, that leppa + recycle/harvest risks pinging the
endless battle clause detector. it's unlikely if you're not actively trying to violate the clause, but there's still a distinct possibility of your opponent having tech capable of triggering it, recognizing they have this bizarre alternative wincon, and positioning themselves in such a way that the ebc alarm goes off, which will make you automatically lose for bringing leppa + recycle/harvest
This is very unlikely, it will only happen if the opponent has at least 2 Regenerator Mons that both take less than 33% from the offensive moves of the Leppa Berry Pokemon. Otherwise, the 2 Regenerator Mons will end up having to spend PPs and progress will be made.
The one Leppa Berry Mon I tried (and got Volcarona Suspect Reqs with) is Hydrapple:
Hydra (Hydrapple) (M) @ Leppa Berry
Ability: Regenerator
Tera Type: Poison
EVs: 248 HP / 248 Def / 12 SpD
Bold Nature
IVs: 0 Atk / 27 Spe
- Recycle
- Fickle Beam
- Recover
- Hydro Pump / Earth Power / Giga Drain
There are no Fairy type Regenerator Mons, so the closest way to avoid the 2HKO would be using a Tera Fairy Regenerator Mon + another Regenerator Mon with AV. The weak link there is the AV Mon, but even the bulkiest one, can lose 33% in a single turn if there are Rocks and Fickle Beam gets the 160 Power hit:
0 SpA Hydrapple Fickle Beam vs. 252 HP / 252+ SpD Assault Vest Slowking-Galar: 91-108 (23 - 27.4%) -- guaranteed 4HKO after Stealth Rock (23 + 12,5% = 35,5%>33%)
In practice, this does mean that Tera Fairy Regenerator Mon and the AV Regenerator Mon can infinitely switch in and out of Hydrapple, but even then, sometimes they will have to spend PPs, so technically its not an Endless battle. This is Hydrapple alone, but he will have some partners to support him with Knock + hazards.
Alolan Exeggutor is less defensive than Hydrapple but will have the benefit of using 3 offensive Moves, due to having Harvest instead of Recycle. Set would be something like this:
Exeggutor-Alola @ Leppa Berry
Ability: Harvest
Tera Type: Poison / Steel
EVs: 248 HP / 252 Def / 8 SpD
Relaxed Nature
- Synthesis
- Dragon Pulse
- Flamethrower
- Knock Off
Other options (designed to hit the Pokemon that resist Dragon): Iron Head (with Tera Steel), Low Kick, Giga Drain, Earthquake, Sludge Bomb (with Tera Poison), Growth, Calm Mind, Dragon Tail. Calm Mind can also be used with Stored Power, but this is really bad vs non Stall teams.
This one is way harder to switch-stall than Hydrapple, since with Knock it will be removing Boots and with Flamethrower, no Steels except Heatran (who is fucked by Knock) will be able to switch-in.
Similarly, Arboliva learns Growth, so no Regenerator core can indefinitely Stall it out, all the Leppa Berry weaknesses come from offense and Knock Off, not from Endless Battle.
Trevenant needs Restalk to use the Leppa Berry, but that also means he is less Tera dependant. Knock Off + 1 of the STABs or Wow can be walled by a Regenerator core, but will will still suffer in the long run, if not vs Trevenant itself, vs its partners.
Tropius is the worst Harvest Mon, but he has all of SD, Growth and DD, so Endless Battle clause won,t ever be triggered with it.
Now, among the Recycle Mons Hydrapple is the strongest one and they have it harder breaking through Regenerator cores. Still, Bronzong learns Iron Defense + Body Press and CM + Stored Power, so he will at least force Tera if Ghost or Dark Mon is not present. Muk's problem won,t ever be from the Regenerator cores, but from Gliscor instead, however he learns Ice Punch, though that means giving up on Sleep Talk and as a result being worse vs everything else. Finally, Snorlax gets Curse, so he will at least will force a Tera even if he can,t break the Regenerator (+Gliscor) cores alone.
