Aerodactyl @ Aerodactylite
Ability: Tough Claws
EVs: 252 Atk / 80 Def / 176 Spe
Jolly Nature
- Stone Edge
- Earthquake
- Stealth Rock
- Taunt
Mega Aerodactyl is very cool for HO teams because it serves several different roles. Having a SR setter that stops Defog AND can check / revenge the likes of EKiller, Ho-Oh, MM2Y and to a lesser extent Mence is absolutely huge. In a meta where scarfers are uncommon and Mewtwo formes are criminally underused, Aerodactyl's ridiculous speed stands out. I use a Jolly nature to outrun MM2Y, although the power drop from lacking an Adamant nature is unfortunate. EdgeQuake coverage allows it to comfortably fit Taunt and SR, ad this Pokemon doesn't have 4MSS in the slightest. There is a more defensive set with Pursuit and Roost instead of SR and Taunt; Fireburn made a team with it and it's an alright trapper since Pursuit gets a Tough Claws boost.
Groudon @ Red Orb
Ability: Drought
EVs: 96 Atk / 252 SpA / 160 Spe
Mild Nature
- Precipice Blades
- Fire Blast
- Dragon Pulse
- Rock Polish
Mixed RP Groudon is a lot of fun for screwing over offensive Mega Mence with Dragon Pulse; often an OHKO after Stealth Rock. Dragon Pulse also 2HKO's Latios and Giratina-O, although this set is useless vs. Latias and Ho-Oh. Fire Blast does a shitton of damage to bulky Arceus, Yveltal, Xerneas, and almost anything that doesn't resist it or is Ho-Oh / a blob. Precipice Blades is used over Earthquake to compensate for the light Attack investment and creams blobs and severely dents Kyogre. I brought this set Week 7 vs. Hack and beat up Kitty multiple times with this in playtesting, but never got a chance to use this. This set is also great on the ladder because Phys Def Yveltal is apparently on every team. I use a Mild nature to ensure this can come in on Kyogre once; not having 194 special defense also helps vs. killer deer.
Alomomola @ Leftovers / Rocky Helmet
Ability: Regenerator
EVs: 248 HP / 252 Def / 8 SpD
Impish Nature
- Wish
- Protect
- Toxic
- Knock Off
Never brought stall in SPL even though it's probably my favorite playstyle at the moment; with my garbage luck there was no way I wasn't getting haxed. Regardless, stall is very viable in ORAS, although I didn't see much in the way of creativity in the builds that did get used. Alomomola is awesome because it's a physically defensive wall in a physically oriented metagame with a great ability, hard-to-exploit weaknesses, and excellent supporting traits in Wish and Knock Off. The giant Wishes it passes are especially useful on teams that do not use Blissey (I often used CM Clefable as a CM Arceus check over Blissey), because replenishing a weakened Ferrothorn's / Groudon's health is huge. This set loses to a lot of Mega Mence, but does good work vs. RP Primal Groudon, EKiller, and Ho-Oh. It's also really hard to kill for opposing Stall while aggravating them with Knock Off, although Magic Bounce users are a hard stop without Scald. Knock Off also 2HKO's Mega Gengar after Rocks, ensuring it can never safely switch in. Big fan of this set, it's a great partner for Ferrothorn.
Other shit I like, but was either used by someone else or have inherent flaws:
Wallceus: Made a RMT with it, similar to Alomomola except it lacks Wish and Knock Off in exchange for better all-around bulk and Wisp. Better on balance than stall IMO, stall wants an Arceus forme with a more useful defensive typing but this Pokemon is a solid backbone.
Pursuit LO Deoxys-A: Used by Kitty, but I made a team with it before seeing him use it. Manly-ass Pursuit trapper but it does forego coverage.
Physical Kyogre: Lots of fun to ladder with, but impossible to justify on Stall or Offense and doesn't serve enough roles for its team to work on balance. I'm shocked more ladder kids don't use this at the very least, with TWave and Waterfall it's a neat CM Arceus check. Also, smacking P Don with Earthquake is hilarious.
Calm Mind Xerneas: Edgar used it, it's a fun set although Pursuit support is almost mandatory for Gengar.
Heat Wave Yveltal: Dice dislikes Yveltal for the most part, but made it work on a team with Heat Wave. Fireburn also used it.
Modest Latios: Much better than Timid for pressuring Steels (especially with HP Fire, which aim also built with) and bulky Arceus; Palkia is OK but almost impossible to fit and Kangaskhan sucks so the speed Timid grants is usually useless. This was Dice's idea.
