Interesting slate; lots of more defensive or disruptive mons which is cool.
Infernape + Prankster: I'm drawn to the Theorymon that does the most new stuff, and Infernape wins that contest. With Stealth Rock, Slack Off, Will-o-Wisp, Taunt and Encore alongside standard moves like Toxic and Substitute and literally every set-up move under the sun, Infernape has a lot of new tricks up its sleeve with its newfound priority. The only drawbacks are that it doesn't seem to have any trick that Sableye doesn't already and Prankster is sort of obnoxious, but Infernape's very different typing and excellent attacking stats give it a different potential niche than Sableye, even if their Prankster options are basically the same. A great Pokemon and a strong contender for my vote.
Milotic + Multiscale: This does less stuff than Infernape, since it basically just makes its current set of Recover/Scald/Ice Beam/Dragon Tail or Haze way, way better, but it might actually be my favorite. I'm a huge fan of Milotic and this is a theorymon I'd thought of myself a few times. Its typing would make it a much better abuser of the move than D-nite, and also a very different, more defensive one. Also, a physical Coil set with D-tail, Waterfall, and Recover also sounds plausible and awesome. She needs Rocks removal, but overall it's an exciting and interesting 'mon.
Liepard + Dark Void: I can see the way the wind is blowing, but I'm going to stick up for my submission. Sleep is obnoxious and mean to be sure, but it's also a part of the metagame, one that Sleep Clause prevents from being totally abusive. Having another viable Sleep inducer (especially one with amazing speed and no reliance on Spore which is easily avoided) would be interesting and I think help chill the meta out a little bit. Prankster is an awesome ability, and it's a shame to see Liepard have no real niche for it that Thundurus, Klefki, Sableye and (in our universe) Froslass don't already have covered. Dark Void would finally put this cool cat on the map. It's far from broken, because in addition to the limits imposed on it by Sleep Clause, Liepard is still kind of a dead weight 'mon. She's got a nice support move pool and U-turn for momentum, but her nonexistent bulk means that a stiff breeze can KO her (nevermind any sort of priority) and while her attacking move pool is awesome, her stats aren't and even at +4 via Nasty Plot she's painfully easy to wall and kill. But she would shake things up and cause some intriguing decisions on the part of both players.
Again, I can see the intense horror here, but I'd ask folks to think about this in terms of how it can affect the meta and what the value of insta-sleep is when considering this submission, instead of focusing on how it would feel to play against. Is it worth basically making your team 5-6 to start in exchange for an 80% to take a key target out of commission for a few turns? How can one best capitalize on that momentum, and gain that advantage without sacrificing all of their own momentum? As an opponent to it, how do you react and "take the hit" from it, assuming you don't have a hard counter? What kind of changes does its presence on an opposing team have for your choice of lead? I think the Pokemon has a lot of interesting discussion in it, even if it you ultimately don't want to give it your vote.
Rock Polish + Nidoking: This is a stacked slate with a lot of interesting Pokemon and to me this one is bringing up the rear. To answer the question, how is it different than Lando?: There are a few big things -
- Different typing: Poison/Ground has more weaknesses but also one more resist (a key Fairy resist), and the King doesn't have any crippling x4 Weaknesses that any sucker with a Hidden Power can prey on. The different resists are nice too: the Rock resist is most welcome.
- STAB Sheer Force Life Orb Sludge Wave + Fairy resist = kill 'da fairies!
- A literally insane move pool with every kind of coverage known to man or Mon. Fire, Dragon, Water, Electric, Ice, Fighting, Bug, and Ghost, on both the physical and special sides.
That might sound like a resounding endorsement, but I find that +Speed booster pokemon are the worst kind of sweepers because Priority ruins their day. Nidoking's best role now is as a Wallbreaker, and I think he's at such a stat disadvantage right now compared to Landorus and to every other big bad MegaSweeper that just Rock Polish isn't enough to make him deadly. Having to run Rock Polish kills his primary advantage over Landorus anyways (dat move pool), chewing up a slot. I think Nidoking needs a buff to be OU competitive, but I'm just not convinced Rock Polish is the way to go. The calculator is down right now though, so I'll check later to see if a more bulky set can tank priority long enough to set up and smash face.
