Those Fighting-Type pokemon rape this metagame fast as lightning.
Speaking of which, the two major concerns this round are indeed Fighting-Types, Meditite and Scrafty to be exact. Both of these Pokemon are great choices for the Standard Little Cup metagame at the moment. Both of them are top tier threats and can certainly punch holes into the opponent's team, possibly even sweeping through it with a single boost along with relative ease.
Meditite is probably my favorite pokemon in this tier as far as performance goes. (and I also hate to come against it ~_~ )
With an offensive LO set nothing can safely come into its bone crushing blows, and on a more defensive Eviolite set, its vastly dependable at checking a big number of threats and deal heavy damage with its amazing ability and can even heal itself at the same time when combined with Drain Punch.
Scrafty is arguably the best set-up sweeper available in Little Cup at the moment, after a single Dragon Dance, very few Pokemon come into Scrafty's great movepool and stop its sweep. With access to not one, but two great abilities in the form of Shed Skin and Moxie, it even widens the chances you won't be able to make the proper move to stop this behemoth from potentially engaging in a clean sweep of your team with the right conditions.
More to come later.
Way to kick this off, Zeph. I agree that out of all of LC, the only pokemon I find to be potentially broken are Scraggy and Meditite. Missy is not as much of a crushing threat as it was in Gen IV, and is not helped by the advent of Speed Boost Carvanha.
Meditite has absurd offenses, that's for sure, and has perfectly usuable defenses with Eviolite equipped, as 24 attack is no slouch even without the boost from Life Orb. With Eviolite, Meditite can run a bulky set with Drain Punch, E-punches, buffed Fake Out, Zen Headbutt, and even possibly Bullet Punch/High Jump Kick. With Life orb, he can revenge a great portion of the metagame with the combination of Fake Out and Bullet Punch with just marginal residual, or even none at all, allowing it to halt sweeps or rack up residual with Fake Out. With absurd offenses, surprisingly bulky defenses (with or without Eviolite), great coverage, and access to priority, Meditite is incredibly powerful. While he can be checked by one of the meta's greatest threats in Missy, who, despite being 2HKOd by Bullet Punch without an Oran Berry when Stealth Rocks are up, possesses a multitude of options to cripple Tite, such as Sub, WoW, or a straight Shadow Ball, he can beat on most of the metagame with his frightening neutral coverage and priority, all coming off of his massive attack stat. For this reason I find him to be significantly too powerful for the standard metagame, and possibly overcentralizing in his minute number of checks/counters.
As for Scraggy, I find that while he can truly be a powerhouse, his ability to consistently sweep is generally exaggerated. The most common set is a bulky one with Eviolite equipped and likely Drain Punch/Ice Punch/Crunch/Dragon Dance, and I will explain later why an LO set is just impractical. With this set he reaches 24 attack and 23 speed, which is equal to that of Eviolite Meditite, to put it in perspective. This fact, combined with the low BP of his two STAB moves in Drain Punch and Crunch, which are 75 and 80 BP, respectively, leave him unable to achieve KOs on nearly anything that he does not hit super-effectively. This leaves things like Croagunk, Hippopotas, Timburr, and most fighting types able to take a Drain Punch and likely KO back with their STAB move of choice. You will also notice that at 23 speed only, Scraggy with just one DD gets easily outsped by many scarfers, notably Mienfoo, and things like Drillbur or Chlorophyll Bellsprout which can do heavy damage to him even through the Eviolite boost with their powerful STAB attacks, such as Earthquake and Solarbeam. Yet one more con to add to this pile is that he has no access to priority, leaving him incredibly vulnerable to moves like Vacuum Wave, Extremespeed, Mach Punch (notable, especially on Timburr), and Fake out, all of which can either add residual damage (in the case of Fake Out) or revenge Scraggy after prior damage from anything from Steel Thorns, Leech Seed, or Sandstorm to the attacks he needed to take when switching in to take advantage of his great defenses or setting up on a poke that cannot OHKO it. While Drain Punch may help significantly in dealing with this residual, it can be avoided by the use of switch-ins like Misdreavus or Gligar, who take extremely little damage, or none at all, from Drain Punch, and offer no hp in return when OHKOd by Crunch/Ice Punch, respectively. And while these only deal with +1 Scraggy, I find that it is nearly impossible to get up two DDs without an extreme prediction error made by the opponent, which is rare considering how cautiously players play around Scraggy as of now. For these reasons I find Scraggy to be a TOP-tier threat, but not quite broken enough to warrant a ban at this point, although he most certainly deserves to have a look taken at him, especially if Meditite is banned this round.
