So I've been pretty vocal about this for a while, but I think that UU is way overdue for a Hydreigon suspect.
Someone asked me to post elsewhere why I thought Hydreigon was all of a sudden ban-worthy after being a UU staple for years, and here was my response:
- Draco Meteor is a stupid, stupid move. It hits so ridiculously hard from Hydreigon's Special Attack that you really can't switch into it without a decently bulky resist (or a Blissey). You can't just pivot in something moderately bulky that KOs in return, because Draco just drops things. Hell, it does 45% to 252/252+ Umbreon (and the popularity of Taunt means that using Umbreon as your special wall is a liability against any team with a Taunt Hydreigon). This is literally THE benchmark Special Attack in UU - Draco Meteor from Hydreigon hits harder than Sylveon's Hyper Voice, +2 Celebi's Psychic or PZ's Adaptability Tri-Attack. It is a nuke, and if the opponent doesn't have a Fairy or a Blissey, there is almost zero drawback to clicking it every time Hydreigon comes in.
- Hydreigon gets really pointlessly good secondary STAB and coverage. Lots of things hit really hard, and I don't think that wallbreakers are inherently broken. But Hydreigon's secondary STAB is ALSO really good, hitting most Steel types hard and preventing things like Cresselia from recovering on it. Plus, you know, Hydreigon for some reason learns EVERY GODDAMNED MOVE IN THE GAME, so it has the ability to punch past every one of its counters. I'm not talking about some hypothetical Hydreigon with eight moveslots. Actual legitimate, functional Hydreigon sets can easily beat common counters, just running dual STABs + Fighting and Steel coverage.
- The rest of its (non-offensive) movepool ain't half bad either. Mostly I'm talking about Uturn, Taunt and Roost here, Roost in particular.
- Hydreigon is actually really useful defensively. In general I don't think wallbreakers are broken. For example - sorry Fuga - I don't actually think Mamoswine is broken, despite the fact that like Hydreigon, it's stupid hard to switch into. The difference, though, is that Mamoswine is both significantly slower (I'll get to that next) and also doesn't really possess much defensive utility. You're almost never switching Mamoswine into attacks not named Volt Switch, so with even a little bit of offensive pressure from the other team, Mamoswine is only ever coming in after something dies. But Hydreigon's bulk is actually pretty good, and its typing is kind of amazing defensively for the tier. When you add in the fact that it's Stealth Rock neutral and immune to all other entry hazards, Hydreigon is going to get multiple switch-in opportunities in most games, which other wallbreakers could only dream of. Entei and Kyurem can both apply similar offensive pressure and are also stupidly fat, but they are hazard weak and have way worse defensive typings for the tier, so again, they're not coming in as freely as Hydreigon. (Oh yeah, and it resists Pursuit, too. Not necessarily the biggest deal, but it adds into how few drawbacks there are to just bringing in Hydreigon and clicking Draco Meteor.)
- Actually decent Speed. I always see people point out Hydreigon's Speed like it's some great flaw. I'll admit, it's excruciating to see something get so close to the base 100 benchmark but not quite hit it, but... really? Hydreigon's fast af, dude. Yeah, it's the second slowest of the S ranks by a hair, but it's still faster than the entirety of A+ and 2/3 of the rest of the tier. I always hate it when I see people argue that you have to choose between beating offense with Scarf or beating fat teams with Specs/LO. Specs/LO might not be as crazy good versus offense as it is versus balance, but they still almost always put in work, especially since most things that outspeed it can't actually switch in. Hell, I just pulled up all of kokoloko's replays from SPL. He almost exclusively played offense, and yet in almost every single week, Hydreigon was as fast as or faster than 4 out of 6 pokemon on koko's teams (and this was in a meta when we had another fast offensive threat in Alakazam).
So yeah, any one of those factors wouldn't be overwhelming, but when you take in how few drawbacks there are to just clicking Draco Meteor, add in its thoroughly ridiculous movepool, slap on the fact that it gets several switch-ins in a game, and finish it off with the fact that it outspeeds a pretty major chunk of the tier, you have something that is really overwhelming. Frankly, I find Hydreigon more problematic to build around than Salamence ever was, because if I'm building anything other than balls out offense, I pretty much HAVE to add Florges or Sylveon to feel like I have a decent answer to it.
So then comes the next question... what changed? I mean Hydreigon has been UU literally for years, so what actually changed for it? Well, I think there are a couple of big factors.
First of all, the common sets shifted and became more centered around sets that take advantage of Hydreigon's best aspect - i.e., its crazy-strong Draco Meteor. During most of my time playing XY and early ORAS, Scarf was far and away the most popular set, with the occasional "lure" Hydreigon with Superpower for Blissey/Umbreon. By UU Open last year, this had largely shifted in favor of LO Taunt Roost, which is around when I personally feel Hydreigon started being really overwhelming. (Not to say Scarf isn't good, by the way - it's a really great set, and Hydra is in my opinion far and away the best Scarfer in the tier.) And now, in addition to LO Taunt (which remains popular), Specs Hydreigon has been seeing more and more use, whereas previously I think it was considered mostly a niche set meant to bluff Scarf and surprise people.
Second, the meta has gotten increasingly more offensive with various drops and shifts. ORAS obviously saw a big jump in offensive threats right off the bat, and tier shifts brought some old standards like Heracross and eventually Celebi back, plus some big new threats like Gyarados, Mamoswine, Conk and Sylveon. Meanwhile, most of the heavy hitters still remain - we've banned Alakazam and Salamence but most of the old standards like Entei and Krookodile still remain. It's gotten to the point where building anything other than straight offense is a really delicate balancing act, since there are so many serious threats to account for. While it's the newer threats that have really tipped things over the edge, Hydreigon is far and away the most threatening (only Celebi really comes close), and is probably the most restrictive on teambuilding. You could ban all the new drops and shifts to make UU less crappy, simply because Hydreigon has a history of being UU - but that's stupid. Hydreigon is more busted than almost any of them (again, the only thing IMO that comes close is Celebi).
So yeah, enjoy that wall of text. None of this is new, by the way - I've said all of this many times (in far smaller chunks) on the Skype chat, in the PS room, etc. For what it's worth, by the way, I believe Hydreigon is actually more busted in this tier than three out of the five most recent UU bans: Salamence, Victini and Pidgeotite. (Yeah, Serp and Zam were more busted, but come on, that's hardly a surprise.)
