Moxie Weavile: This is definitely one of my favorites. Weavile is already a pretty solid revenge killer, but adding Moxie makes it so much better. Thanks to its high Speed and access to Pursuit, Weavile will likely get a Moxie boost quite often, making it not only a great revenge killer that can stick around after getting the kill, but can also be an excellent late-game cleaner. Sacking something to get a safe switch can put the switch-in at a disadvantage, ans trying to switch out means that Pursuit can be a problem, so some mindgames can ensue. Really, I think that this is the best ability that Weavile could have gotten other than the cliche stuff (Tough Claws and Refrigerate), and I'm really liking it.
Sand Rush Cacturne: Having Swords Dance and Nasty Plot, respectable 115/115 offenses, a fairly wide movepool with good offensive and supportive options, and the new Sand Rush, Sand Rush Cacturne looks to be a powerful new threat. Sadly, the lack of any durability will make it hard to pull off a sweep, as even though it has good offenses and boosting moves, a) it isn't the hardest hitting thing out there, 2) its pitiful defenses will leave very few opportunities to actually set up in the first place, 3) 55 Speed is kind of low, even with Sand Rush, so Choice Scarf and Dragon Dancers can get the jump on it, and 4) Talonflame completely derails this thing from a sweep. But it does have some useful support moves in Switcheroo, Destiny Bond, and Spikes, so it wouldn't be all bad, and having something to take on Water-types is great, as some sand teams struggle against things like Keldeo, Rotom-W, and Azumarill. I can actually see a Choice Band set working here, with Seed Bomb / Sucker Punch / Low Kick / Switcheroo being pretty effective, and if Specs is what you'd prefer, then Energy Ball / Dark Pulse / Focus Blast / Switcheroo is almost as good. This wouldn't be a top-tier threat, but it would definitely be a great help to sand teams. I would honestly say that this would be just as good a Theorymon as Moxie Weavile.
Spikes Pidgeot: I can see this one working. Mega Pidgeot always needed some support to soften foes before going on a sweep, so why not let it support itself? With Spikes, Mega Pidgeot can set up when the opponent brings in a check/counter, switch out with U-turn, and keep the pressure on the opponent. Even if you can't KO the check/counter after the Spikes damage, the fact that they have to switch in and out means they'll gradually lost health from both the passive and direct damage until Mega Pidgeot can KO them after they switch in again. I'm not a huge fan of this one, but neither I wouldn't be surprised to see this one win.
Electrify Zebstrika: This seems broken at first sight, but it's more annoying than broken. With Electrify changing every attack to Electric and with Zebstrika's ability Lightningrod, Zebstrika theoretically can't take any damage so long as it's the faster Pokemon on the field. Mega Heracross' Close Combat? Latios' Draco Meteor? Even Toxic? Zebstrika can turn those into golden setup opportunities by absorbing their attacks and raising its Special Attack in the process. 116 Speed also helps here, as not even Starmie can get the jump on Zebstrika. But Zebstrika can't absorb what isn't being thrown its way, so setup sweepers can safely set up while Zebstrika wastes a turn waiting for an attack; this especially applies to Calm Mind sweepers. Substitute can be used, but giving up coverage to force the opponent to attack is questionable. Zebstrika also has the issue of having slim defenses and low initial Special Attack, so it really needs a boost to get anything done. There are also faster threats out there to ruin the strategy completely, like most Choice Scarfers, Mega Lopunny, and Sand Rush/Swift Swim users. Not as OP as I first thought, but still a cool idea to play with.
