dump of my notable bw teams for the year + i talk about defiant thundurus specifically. the defiant thundurus sets on pastes have changed a bit from the ones in replays as i began to favor LO + Crunch over Fighting Gem + Sky Drop

Weatherless Moth Balance - DPL7 Week 4 vs DaWoblefet / BW Cup vs Yoda2798






The idea going into the match-up was I generally wanted to be instantly advantageous against the Amoonguss balance teams which I was highly putting DaWoblefet on. At the same time, I wanted to make sure that I had strong answers against Skymin as I recognized that my own usage history can make it look like I'm vulnerable to it. Quiver Dance Volcarona fits within both ideas as it's a great balance breaker and can render Shaymin-S moot at +1. Defiant Thundurus and Expert Belt Cresselia are also attempts at beating balance; the former is handy for getting surprise quick damage on Tyranitar and Heatran, while Cresselia can make sure Amoonguss, Metagross, and Hitmontop can never get too out of hand. Scarf Kyurem-B is there to make sure Scarf Landorus-T is invalidated, and it's also nice for keeping Latios at bay. Jellicent and Amoonguss round the team out as a defensive duo that can generally deal with everything, in particular being key for the match-up against rain; while I do have Cresselia, it's not as reliable defensively due to how its EVswere invested. I typically never use weatherless in BW DOU and this might be the only team I have of the sort within the past three years, but I'd say this is a pretty solid attempt.
Scarf Tyranitar + Keldeo + SD Scizor - DPL7 Finals vs DaWoblefet






This one was also for DaWoblefet but now for the DPL finals matchup. While I still had the balance match-up in mind as it really did feel like DaWoblefet's style, this time I was more wary of how I deal with Kyurem-B on either of its two better sets. I went with SD Scizor, again another set-up attacker as they're good breakers against balance, but also because it's inherently good against a lot of balance pieces such as Latios, Metagross, Cresselia, TTar, and Amoonguss. Keldeo is a curious addition as it's not really common, but I really like it as it can reliably decimate Heatran while still putting heavy pressure on KB and TTar (for Latios); Latios is used in the same vein, except Draco Meteor destroys everything instead. Choice Scarf Tyranitar is there to make sure opposing Latios don't become too problematic, as it's still capable of just nabbing one every time. I'm using fast bulky Thundurus in order to maximize my range in stuff I can Sky Drop, which can be really handy in getting surprise unpins on my attackers. I genuinely like this team as I feel like it's a good attempt at maximizing Scizor while not being too exposed by Heatran and Jellicent.
The Six but it's Defiant Thundurus - BW Cup vs Yoda2798






It's the six. But it has Defiant Thundurus. I talk about Defiant Thundurus specifically later on this post, but in the context of this team I don't think it actually needs Prankster Thunder Wave as the rain match-up isn't that bad, considering it has Jellicent, Latios, and Tyranitar. What the team does appreciate, however, is more aggressive options in dealing with Latios, Tyranitar, Kyurem-B, etc..--iThundurus's handy for taking advantage of what would generally be average matchups into surprisingly daunting pressure and pins, which in turn helps me in positioning with my other 5 which are quite in dealing with a broad range of stuff by themselves already. The rest are pretty simple as they are essentially the default sets.
[DEFIANT THUNDURUS]
I have been using Defiant Thundurus throughout DPL and Classic and I can honestly say that it's a real valid set for BW DOU. It's been a generally effective pick from my experience and is basically not a meme.

Thundurus (M) @ Life Orb
Ability: Defiant
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Wild Charge
- Crunch
- Superpower
- Protect
The idea with this set when I first tried it out is that Prankster Thundurus typically baits out stuff like Tyranitar and Heatran, stuff which this particular set can obliterate. Teams usually don't want their offensive stuff Thunder Waved, so they usually send out their slow, bulky stuff which this set can more effectively punish with significant damage. As Prankster Thundurus and Defiant Thundurus essentially have to be dealt with in different ways and with different checks, I wanted to take advantage of this fact by using it to make quick picks, opening up opportunities for other guys; this kind of surprise element for me was valuable, especially since DPL was only a best-of-1.
Still, this set had consistency even with it being within my meta. It's strikingly effective at keeping a lot of key threats at bay with pure offensive pressure, owing to the fact that it's faster than Latios and how its coverage lets it hit a lot of key Pokemon in the metagame super effectively. Wild Charge hits hard enough neutrally as LO Thundurus still has the raw attack to be respectable and it notably hits Jellicent for SE. Superpower decimates TTar and takes a fat chunk out of KB and Heatran. Crunch is literally only for Latios but this is still valuable as Latios is one of the most daunting threats in BW DOU and is almost always in every non-rain team. All of the threats I mentioned here are Tier 1 threats. I've found that teams often just resort to using Intimidate when it comes to dealing with physical attackers, which this set punishes; as long as Thundurus has teammates that can keep Landorus-T from Rock Sliding e.g. Wide Guard Hitmontop, Scarf Kyurem-B, then it can basically wreak havoc on most opposing balance teams.
While it does have Defiant as an ability, a lot of this set's value isn't even about punishing Intimidate. Rather, it moreso comes from how it has the super effective coverage on a lot of key targets in the metagame on top of the fact that it can be a bit of a puzzle to tell apart whether a team has Prankster or Defiant from preview. Defiant Thundurus isn't necessarily a strong (physical) attacker in its own right, but it nevertheless is quite effective, this effectiveness being a product of the metagame. As long as balance teams still look like they usually do, this set should still be quite effective and I definitely recommend people give it a try if an opportunity to play BW DOU comes around.
