Shiinotic @ Red Card
Ability: Effect Spore

Calm Nature
- Strength Sap
- Protect/Toxic
- Leech Seed
- Giga Drain
It's not like this is a super-annoying-impossible-to-beat-stall, but it's pretty solid and can deal with at least 2 Pokemon before fainting. I don't know if I really need to explain the moves. I think you can figure it out. Use Protect for a free healing turn, or Toxic for extra damage. Great set.
Toxapex @ Black Sludge
Ability: Regenerator
EVs: 252 Def / 220 HP / 36 SpD
Bold Nature
- Block
- Baneful Bunker/Scald
- Stockpile
- Recover
This is more of a troll to me. Block makes it so they can't switch out on you, so as soon as you set up Stockpile, spam Recover and annoying them until they rage quit. That's the whole strat. I got up to 1500 on the ladder on Showdown! by making people forfeit.
