Lemme throw a couple of more in.
Mientwo
Mewtwo-Mega-X @ Life Orb
Ability: Regenerator
EVs: 252 HP / 252 Atk / 252 Def / 252 SpA / 252 SpD / 252 Spe
Jolly Nature
- High Jump Kick/Low Kick/Close Combat
- Diamond Storm
- Knock Off
- U-turn
This set is basically a Mewtwo-X that thinks it's Mienshao. And it works quite nicely, actually. Offensive Regenerator is really an overlooked strategy that allows a Pokemon with already good power, such as Xtwo here, provide constant pressure on the opposing team without needing to stop and heal, rely on Wish support, or fear getting worn down. Additionally, it can use the Life Orb with little risk to its longevity, something that a lot of other Pokemon wish they could say. Although if you need a different item, like a Choice Band or Safety Goggles, then by all means.
The Fighting-STAB of choice depends on preference. Close Combat is the most reliable, but also makes Xtwo rather revenge-killable. Low Kick hits a lot of things just as hard, but also tickles some other threats. High Jump Kick has nice power, and is great if you have a Spiky Shield, King's Shield, or safe Ghost switch-in to an Imposter, but it also risky for the same reasons. Beyond that, Diamond Storm allows this set to hit most Fighting resists, mainly Flying, Bug, Ghost, and Psychic, all for neutral or super effective damage (except Aegislash). Knock Off provides more coverage, again hitting all Fighting resists, notably including Aegislash, while providing item removal support and high damage. Finally, U-Turn is a handy tool for scouting, maintaining momentum, and escaping from trapping. Of course, if you need different moves for coverage, like Bolt Strike to deal with Kyogres who annoy your team, then again, by all means, as this set is flexible.
It should be noted that this does not have the power of a wall breaker or a set-up sweeper. That's fine because that's not its goal. Its job is to maintain consistent, offensive pressure to wear the opposing team down. If it can get some KOs along the way, then even better. But generally, it wears things down so something else can clean-up.
Kyoltal
Yveltal @ Toxic Orb
Ability: Poison Heal
EVs: 252 HP / 252 Def / 252 SpA / 252 SpD / 252 Spe
Modest Nature
IVs: 0 Atk
- Oblivion Wing
- Dark Pulse
- Quiver Dance
- Spore/Dark Void
I've been wanting to post this set for a while now, but I had been holding off since I hadn't used it under any of my known alts until recently. This is quite an unexpected set to run into as most people think you'll be using the usual defensive Yveltal (Koff / King's / Circle / filler) or the offensive, Bird-spam Yveltal once they see that Toxic Orb go off. As such, people tend to switch in their Aggrons and other, physically oriented responses to those sets, or switch out things that'd have a chance against this one but not the others, giving a free set-up opportunity.
As you could expect from the given moves, this set plays similarly to Adrian's Kyogre set. Put things to sleep and start setting up. But it's only similarly, not identically. While Kyogre wants to keep it's HP high in order to smash stuff with Water Spout, Yveltal can make itself very difficult to KO by the powerful healing effect of Oblivion Wing coupled with Poison Heal. Therefore, while Kyogre can be rendered a non-threat by the proper check hitting it hard enough soon enough, Yveltal can just siphon it's HP back. Though, I'll be fair, Kyogre's damage output is much higher, so this set isn't necessarily superior, just an alternative.
Anyway, Dark Pulse is used over Night Daze, normally something I'd advise against, because this set is meant to counter Imposters on its own and the last thing you want is an Imposter forcing you out because of accuracy drops. Still though, Night Daze can be used if that doesn't concern you. Additionally, either STAB can be replaced with coverage if you need to, but Flying/Dark provides quite nice coverage as is, only notably resisted by T-Tar off the top of my head, and Yveltal will sorely miss either move. (Sustainability from Oblivion Wing, ability to remove stuff that otherwise laugh at most PH Yveltals with Dark Pulse, such as Giratina, ironically enough.)
