I built this team for UUSD and I liked it a lot, so figured I'd post it here.






The team was originally built around Thundy-I, so I added this as its Ice coverage pairs extremely well with Electric, notably hitting some of its checks like Meowscarada and Hydreigon. Weavile in general is just extremely speed-control as it can easily outspeed and one-shot the two fastest mons in the meta besides it and Knock is excellent at making progress.

The one thing this does well over its Therian form is Nasty Plot as it can outspeed Iron Treads and its power is just good enough to get one shots on Iron Treads and Amoonguss at +2. Teams who rely on Treads and Torn for their speed control usually struggle a lot with this mon as it can tear apart defensive cores and doesn't care for Torn. It pairs very well with Weavile as Meowscarada and Hydreigon can be annoying for Thundy, but fast Ice moves can force them out and give you advantage. Thundurus brings Electric coverage to take out Water types that attempt to check Weavile like Quaquaval, Azumarill or Volcanion. The one weakness this offensive core has is that Electric types and Tera Electric mons like Bellibolt, Tera Amoonguss and Tera Tornadus-T can be quite difficult to break, though not impossible since they don't tend to be so instantly threatening as to prevent you from making progress forever.

At this point, I knew I'd have a team that's a bit weak to Weavile and Arcanine-Hisui, so I went with Roost Quaquaval. It barely has any defensive investment, but it doesn't need much to help out against those and I dislike giving up the sweeping potential for Spin sets as I find those to be easily taken advantage of. Its lack of coverage is a bit unfortunate, but the rest of the team can properly pressure Slowking, Amoonguss and Sinistcha, so it's not that bad. Tera Steel+Swords Dance to +4 is also the team's Cresselia answer lmao.

Quaquaval isn't a real Water answer and I wanted a solid Meowscarada switch-in since Thundurus lets it in easily. This is the switch-in to opposing Quavals, Azumarills, Rain wallbreakers and Grass types, pretty simple. Unfortunately feels a bit passive at times, but it's pretty much required on this build I feel.

Here is Rapid Spin+Rocks dude. I do like having some way to apply offensive Ground-type pressure at least since, as I said, Electric is a bit of an annoying type to break through for this team offensively. You know what this does though, no need to spend more time talking about it than we need.

The switch-in to special attackers, especially Hydreigon, and a good way to position the offensive threats. Makes for a good Regen core with Amoonguss if you want to play a bit slower. Again, very standard glue, not much more to say about it.
Extra info matchup-wise: This team is good at breaking standard BO and Balance teams as those tend to lack good hard-walls to the Weavile+Thundy offensive core and they'll take a while to get through Amoonguss and Torn. However, this team is not quite as good at dealing with Hyper-Offense and Fat. It can get overwhelmed rather quickly by certain setup-sweepers like Iron Hands, Hydreigon or Moltres-G and defensive teams will usually force you to get through Skeledirge which is realistically only possible through Knock Off+Hazard pressure. It tends to perform fine against Rain though.
