That could work. I'm kind of feeling Togekiss in the last spot instead, to better take out Mawiles with Flamethrower, and maybe just run the Para-Flinch/Recovery with the rest of its move slots, which puts even Azumarill in a bind. There's probably a way to EV it to make Aqua Jet at least a 3HKO.
I want to do this, but I'm not sure I'll have time in early September to breed a team for it with grad school starting. Although if I can snag a cloned Mawile and just temporarily replace some moves on an existing Klefki I use, I'd only need to breed for Togekiss. We'll see.
Also, I see Trick Room being really questionable here with everyone running their own Mawiles and Prankster Pokemon, but maybe I'm not thinking that through. I wonder if it'd be worth using a Brave Mawile even if you aren't using a Trick Room team of your own, just in case.
I can get you a cloned careful one immediately (not sure if it'll be good for this meta, though), and I've got an adamant already bred that needs to be EV'd and leveled. If you or someone else wants to talk about what a good EV spread would be, I'd be interested. As of right now, the best I've got is 252 HP / 252 Atk / 4 Sp.Def (with absolutely 0 thought behind it, lol). Though, if being able to out-speed mirror mawiles is a thing, would 252 speed be worth it?
I think a big threat will be swagger!bot klefki. This meta is particularly weak to parafusion. Can aromatisse's ability block confusion?
I think aromatisse and carbink will see some use as TR setters for mmawile. For example I could imagine this being successful:
Carbink @
Custap Berry (I wish) Mental Herb / Normal Gem
Ability: Sturdy
EVs: 252 HP / 252 Atk
Brave Nature
IVs: 0 Spe
- Trick Room
- Explosion
Sturdy guarantees you'll live a hit and get TR up,
custap berry if you intend this against a predicted priority abuser, like mmawile, who would snipe you after bringing you down to sturdy. Mental herb to get TR up safely without worrying about a taunt, or normal gem to do more damage with explosion (normal gem is a great option if you also have aromatisse on your team). Explosion to deal some damage before you get out of the way for your own mmawile to safely come in.
The team would work best with aromatisse as well, as just the presence of an untauntable TR setter in team preview could shift your opponent's choices of what to bring. Bring the TR setter that best fits the situation. Dunno a good build for aromatisse off the top of my head, though.
EDIT:
ethan06 Might want to keep sucker punch on mmawile just to snipe focus sash'd pokemon.
EDIT2: Updated the set due to remove custap berry.
