U-turn
When it comes to Prankster rain users, there's probably a lot out there (even when considering you'd also want additional utility like taunt and encore), but my eyes set on Volbeat because it has access to slow u-turn as well, a pretty valuable tool. It's bulk is not horrible when taking the tier shift boost, enough to survive 1 or 2 hits usually. Although this team is extremely offensive, so even if you have to sack Volbeat after getting rain off turn 1, it's usually fine. Taunt is really important to stop something like webs or screens from going up, and Encore can be useful in a pinch. Not really any point in running Roost because the only thing Volbeat is there for is set rain up then die anyways, and we have secondary rain setters anyways. Speaking of which...

Nasty Plot
Tornadus is really strong in Tier Shift, boasting an impressive 150 base SpAtk, backed up by 110 bp Hurricane and 100 bp sort-of stab Weather Ball. It's ability to reset rain at +1 priority also comes in handy very often. You usually won't be clicking Nasty Plot very often, as Tornadus is not exceptionally bulky despite the +25 to both defenses, but it really helps crack open fat balances you may run into (for exemple, you might wanna click it on a predicted Vaporeon switch in). Very solid offensive mon with a decent bit of utility.

Belly Drum
If you know me, you know I love Poliwrath. I've been using it in SV OU as part of a pretty wacky offmeta rain team, but this time, he's playing with the big boys. I'm using an all out offensive set here, dropping Encore in favor of Ice Punch for coverage and CC in lieu of Drain Punch for maximum breaking power. Poliwrath is already surprisingly bulky in SV OU, but with the amazing +30 all over boost he gets here, you can easily set up Belly Drum in front of any Pokemon that can't hit you super effectively. Just like Tornadus, this is great vs any fat balance you may encounter.

Usually the star of the show in most rain teams, today Barraskewda is playing second fiddle to our next mon. Still, he's really solid and gets a very nice boost. Rain mons tend to have pretty low usage/tiering, which doesn't really reflect how strong they can be; which is how you end up with 146 base Atk Barraskewda. This thing is kind of a monster, but the popularity of Vaporeon makes it a little difficult to use sometimes. I'm running max speed which is way overkill under rain just so you have something that remains fast once run is out/if webs go up. Not much else to say here, this is as classic as it gets.

THE GOAT!! Gunk Shot hits disgustingly hard, being a guaranteed 2hko on full defensive Amoonguss. Overqwil is a very nicely rounded out Pokemon in Tier Shift, with great natural bulk that allows you to set up SD very easily. But most games, that won't even be necessary: You're ohkoing anything that is not fully defense invested anyways. If drizzle wasn't already banned, I'd be saying this mon would probably need a suspect of its own lol.

Since we're on manual rain, we can never have too many setters. Not running Alluring Voice means that this won't be able to dent the usual dragons of the tier (Cyclizar, Etern), but imo the tradeoff is extremely worth it. The combo of electric + water is near perfect coverage anyways, as grass types are pretty rare, and you can volt on anything that switches into you anyways. Excellent at keeping momentum in your favor, and can always come back for the sweep in the late game (although this is true of every single mon in this team, as they all boast excellent speed tiers). A perfect way to round off an already giga offensive team lol
Have fun with this ! As for the suspect, I honestly don't think any of the ubers are really worth it except maybe Caly-I (but I still only have a very limited understanding of this OM in the grand scheme of things). Probably gonna vote do not ban on the Ho-Oh suspect, unless something makes me change my mind. Maybe it's annoying to deal with for Balanced teams, but it is my sincere belief that atm HO teams are probably the best thing you can run atm lol
