Here's a little meme combo that I've had okay success with. Beats weather other than hail, beats electric terrain spam, and beats the m-banette + Whimsicott meme. Only loses to some ghost teams, hail teams, or kyurem-black with the right partner. In general, it's suprisingly robust. I've currently peaked at 1527 ELO with this squad
Here's some replays showing both combos
https://replay.pokemonshowdown.com/gen72v2doubles-822905101 (1527 elo)
Zo (Togedemaru) @ Shell Bell
IVs: 0 HP / 0 Def / 0 SpA / 0 SpD
- Iron Head
- Fake Out
- Spiky Shield
Rajon (Bruxish) @ Wacan Berry
EVs: 252 HP / 4 Atk / 252 SpD
IVs: 0 Spe
- Trick Room
- Aqua Jet
Togedemaru is a standard FEAR mon with fake out. Bruxish is the perfect pairing for toge, as it can set up trick room, protects toge from priority which is very common in fake out, and has access to priority itself.
The main strategy is to fake out the most threatening mon to Bruxish turn 1 and set up trick room. From there, endeavor + bite will kill most opponents. If both opponents have the ability to 0hko Brux, then the alternative is to protect with Brux, and use endeavor turn 1. After that Brux can finish the last damage with aqua jet and toge can start on the next mon. If facing kyurem it's important to target it first as it can kill through Toge's sturdy.
Certain mons are slower than a min-speed Bruxish, which can disrupt the strategy. Iron ball is an alternative over Wacan berry to beat those teams. Though, electric attacks are very common and I think Wacan berry is overall a better item. Mega-mawile is an example of a pokemon that can disrupt the strategy, but it can be played around. If Brux and toge could trade their fake out and trick room with each other everything would be better.
Bite + Iron Head provides good flinch hax + a super effective move if you have to fight a ghost
For laddering, I've paired this combo with M-lopunny and Hoopa-U in order to beat ghosts, kyurem-b and most hail.
Kuz (Lopunny-Mega) @ Lopunnite
EVs: 252 Atk / 4 SpD / 252 Spe
- Fake Out
- Iron Tail
- High Jump Kick
- Fire Punch
Lance (Hoopa-Unbound) @ Choice Scarf
EVs: 252 Atk / 4 SpA / 252 Spe
- Hyperspace Fury
- Grass Knot
- Gunk Shot
- Ice Punch
Only thing that's not straightforward about this combo is that hyperspace fury allows hoopa-u to break other pokemon's protects which can also let Lopunny hit through it. Punny also has access to fake out that can hit ghosts which is cool. Hyperspace fury smacks all the ghosts that Toge loses to. Grass knot is for swampert. Iron Tail is for alolan ninetales. High jump kick Kos Kyurem-B.
