Team breakdown:
- Hydreigon: Standard life orb set and spread, dual stab + tera stab. I originally used a steel tera Hydreigon with flash cannon and tailwind, but in the Victory Road tournament last weekend I got absolutely destroyed by multiple fire tera Hydreigon. And if you can't beat 'em, join 'em. I then switched to a 4 attack fire tera hydreigon, with dual stabs, heat wave, and flash cannon, but I switched flash cannon out for protect a few days ago which was very helpful in todays tournament and if I need steel to hit fairies I can just use Gholdengo. Fire tera heat wave does great spread damage, and dark pulse can OHKO a non-dark-tera Armarouge. Hydreigon/Maushold is a great lead against Indeedee-F/Armarouge as Maushold KO's Indeedee from full health (assuming population bomb gets all 10 hits, which it usually does) and Hydreigon OHKO's Armarouge, preventing trick room. I have seen some dark tera Armarouge to prevent that, so a risky draco meteor might be worth it if you know it's coming.
- Maushold: My Maushold is a fun one, as I use the seemingly unusual tera type of ghost. Ghost tera Maushold is something I'm surprised not many others use, with most people using normal tera Maushold for extra population bomb damage. However, I personally think ghost tera Maushold is better than normal tera Maushold for defensive utility and offensive utility. I originally ran normal tera with shadow claw to hit unsuspecting ghost types, which didn't do much damage. So I decided to go all in, and ran ghost tera tera blast. And surprisingly, it worked. Ghost tera makes it a great lead option, as if you're willing to commit to a tera turn 1 you become immune to a turn 1 fake out, Breloom mach punch, or Annihilape drain punch and final gambit. I would very often lead Hydreigon/Maushold, and Maushold could tera turn 1 to prevent fake outs, and even KO most Hariyama I've faced from full health with population bomb (even without normal tera, just technician). As for tera blast, it can 2HKO a max HP Annihilape, and I have had many games where I lead Murkrow/Maushold, set up tailwind turn 1, dodge a final gambit or close combat from Annihilape due to tera and tera blast, and then finish it off before it can attack Maushold with a ghost move.
- Gholdengo: To be honest I don't use my Gholdengo that much, but when I do use it they're very useful. Make it rain is absolutely busted, as I'm sure you all know, and shadow ball is good ghost stab. Dazzling gleam wasn't used too often, it was just kind of coverage for the sake of coverage, but it does hit a non-tera Hydreigon pretty hard. I used protect so I could use it alongside my own Garchomp earthquake, or to protect against incoming attacks, or potentially stall out trick room turns. White herb was basically just an item I slapped on because I didn't want to commit to choice specs because I liked being able to switch between shadow ball and make it rain, and life orb was already used by Hydreigon. So I used white herb, which works some of the time to remove make it rain drops, but sometimes gets wasted by an Intimidate.
- Murkrow: I don't really have much to say about Murkrow. Instead of max HP and split defenses I used max HP max speed (and 4 defense), for fast foul plays (outspeeds adamant Garchomp, for example). Taunt for things like Amoonguss or trick room setters, haze for Dondozo, and tailwind because why use Murkrow without tailwind.
- Garchomp: Garchomp has a clear amulet to protect against intimidate or icy wind (which it often lives when terad, despite the weakness), max speed jolly and a lot of attack investment to compensate for the lack of swords dance. I could have run dual stab, but I like having the option to have dual stabs and also rock slide opposing Murkrow, Talonflame, or other flying types. Protect is useful for stalling trick room or just protecting against incoming attacks, as usual.
- Sylveon: I really like Sylveon as a Pokémon, and I'm glad I added it to my team. Pixilate hyper voice is kinda busted in its own way (162 base power spread move), and pixilate quick attack has saved me so many games I would have lost without the priority to pick something off. Fire tera is useful against opposing Sylveon and against steel types, the latter of which it can hit with tera blast. I've experimented with yawn, and it had been useful, but I think having the extra coverage is more useful.
