While I have already submitted the mono ghost team in earnest (genuinely one of the most consistent H.O.'s in gen 9 and easily got to rank one with few to no losses and very fun to use) and the mono-rock as a meme submission, there's one more submission I'd like to add: Assault Vest Dialga Offense
. Here is the pokepaste if you want to import and use for yourself: https://pokepast.es/3d32c9dd01ef0584. I'm not going to waste my time with a full RMT as this took 10 minutes to build and wasn't anything particularly challenging, enlightening, or surprising. And what I mean by that is offense has been a viable strategy for a long time, even as certain people in the community choose to deny its existence and viability. Who knew that the strategy Cityscapes has been successfully using in tours and consistently topping the ladder with is actually viable, crazy indeed. And, no, it also isn't something crazy or esoteric that only Cityscapes or Akira can use consistently. It took me a whole 10 minutes to make a viable offense team and top the ladder with it, and I haven't even built a team that wasn't for some cruel and unusual laddering challenge in ages.
Team Synopsis:
Basically, a hybrid between a tank and a mixed attacker. Its bulk means it can come in on a lot of Pokémon, especially special attackers and just start clicking buttons. The great thing about this is that in most cases, your opponent's attempts at a switch in straight up will lose to Dialga. Registeel and Celesteela are straight-up KOed by Gigaton Hammer into V-Create, Ting-Lu takes 85% upon switching in and taking a Gigaton into a Clanging Scales, Kyogre doesn't fare much better, and Chansey just gets paralyzed by Nuzzle. Sure, an opponent can try bringing in their Fur Coat / Take Heart Arceus, but they can easily have half their health removed by Clanging Scales.
Basically just stops Take Heart abusers from running rampant with a strong Thunder-Cage and leftover recovery. It also occasionally functions as a late-game wincon once physical attackers and set-up control on the opponent's end is removed, and Imposter-Proofs Dialga if it gets too weakened by stray hits.
A temporary physical tank to check physical attackers. It uses no recovery, so an Imposter's best case interaction with it is that it gets paralyzed and loses HP from Steam Eruption. Also sets Sticky Web for the team's physical breakers, so the rest of the team is much harder to offensively check.
The team's main Strength Sap blocker and hazard control. Also puts on a lot of offensive pressure and is difficult to interact with defensively, thanks to a high attack stat and Good as Gold / Covert Cloak.
Just the standard Tough Claws Shift Gear set. Consistently does massive damage to Fur Coat walls even without setup due to high attack and massive BP on its moves.
Since the team only has Glare / Nuzzle for set-up control, Blaziken serves as a contingency plan with Destiny Bond and Copy-Cat. Other then that, it can put massive offensive pressure with Swords Dance and V-Create. Imposter-Proofed by trading itself with Imposter and by Arceus Water.
How to play the team:
Before you lead, look carefully at an opponent's team. If you expect an Imposter or physical breaker lead, then Arcueus Water is the correct option. If you expect a regen-vest lead bring in Chomp. Lastly, if you expect a special attacker to lead, go into Dialga. With this team, you don't want to switch around and play passively. Be sure every play keeps the opponent on the back foot and low on HP. Once you've weakened and sap-blocked physical walls, go for the win with one of the team's physical sweepers as soon as possible.
Proof of Peak:
My alt is Mr. Natas 666, and as can be observed, I got to rank 2 with ease. I could've easily gone for 1700 or even 1800 with this team, as it was overall incredibly consistent; however, because of my elo, I was spending more time in the queue than actually playing, so I think I'll stop here for now.
Note: While this was the alt I used for the mono-rock challenge, I didn't start at 1582 elo, but below 1400 for this team at a terrible gxe. This was because I was testing ideas for the challenge of reaching rank 34 on the ladder with an r34 theme team. As one can imagine, it did not go well.
Another Miscellaneous note and hot take on sample selection: Easy to use should not be used as a criterion for sample selection, it is basically just codeword for familiar/ in the style of the council members, and so even teams with good performance get discarded in favor of teams that are more familiar to the council but overall worse in quality and performance. Also, enjoyable to use should also be a criterion. Just look at the blunder video, nobody wants to play those awful regen-cycles (especially newer players).
