Ludicolo @ Leftovers in doubles with Rain Dish and Leech Seed + Protect.
Pretty decent defenses, gets 8 HP boosts for every time it's attacked.
Toxic and Seismic Toss next to the Rain Dance makes it so you can dish out 100 HP damage while they're poisoned and keep healin'. A partner with the Rain Dance or Drizzle opens you up for another move slot if you want, like Rest or Giga Drain or something.
It's pretty fun. I've been doing it since RSE. I got pretty far in the VGCs back then with a team based around that Ludicolo lol.
