Wobbuffet: Now, lots of people keep saying that Wobbuffet isisn't as effective this gen because of the Encore nerf and stronger attackers. Those may be true, but they really don't hinder Wobbuffet enough to make him not broken. Unless your running a team of Pokes that can all OHKO Wobb, he can still Encore that Poke and than either Counter or Moiior Coat it back if it won't 2HKO him, or switch out to something else that can take advantage of the locked in Poke if it was a support/resisted move. Now, there may be other Pokes that can Encore or CounterCoat, but what really makes Wobbuffet so great at it is Shadow Tag. It ensures that after Wobb has Encored your opponent, they won't just switch out unless they have U-Turn, which can be Countered to hit the Poke coming unless it's a Ghost, Volt Change, like U-Turn, but Mirror Coat instead of Counter, Baton Pass, or the Poke is equiped with Shed Shell, which means they can't use a much more usful item like Leftovers or Life Orb. Because the general disturbition of the moves are small and Shed Shell frankly not anything else but letting you switch out of Wobbuffet, means you'll often be able to take advantage of them, which can easily spell your opponents defeat in this metagame. Wobbuffet also makes trying to revenge kill threats with Choice Scarfed Pokes much risker because unless the move they tried to use to revenge a threat is very strong, Wobb will just CountCoat it back and than your sweeper can sweep without the threat of a revenge killer.
Darkrai: The new sleep mehcanics will pretty much gurantee that Darkrai will render one Poke usless unless its specfically used to counter Drakrai or is a Sleep Talker, which is quite rare this gen. Adding on to this, Darkrai can than switch out, its main job done, or he can set up a Sub or Nasty Plot to try and smash the opponents team. It can also run a Choice Scarf+Trick combo with Dark Void to mess up the rest of the opponents team (i've presonally crippled half of someones team with just Trick and Dark Void). Heading back to Nasty Plot and Sub, Darkrai has an absurdly easy time setting up either because of Dark Void. Nasty Plot rips through teams without something faster, a special wall, or priority. even than, Darkrai will need to be weakened by entry hazards or weather to be able to KO him with Mach Punches from Roobushin, the most common Mach Puncher in the tier. Substitute ensures Darkrai will get an attack off and possibly a kill before the Sub is broken, where Darkrai can just switch out and start the cycle all over again.
Skymin: Basically, Skymin is Jirachi and Togekiss with better Speed and Special Attack. There are 11 Pokes that can outspeed Skymin without any sort of Speed boost. They are Meloetta, Crobat, Jolteon, Mewtwo, Aerodactyl, Electrode, Agirudaa, Ninjask, and all the Deoxys Formes besides Defence. Out of that list, only Crobat, Jolteon, the Deoxys formes, and Aerodactyl can KO Skymin and are viable in this metagame or not banned. This assumes that Skymin isin't holding a Choice Scarf, which means she can defeat everything but Crobat if she decides to use one. Choice Scarf also allows Skymin to outspeed all the Swift Swimmers and hit them back with Seed Flare and Air Slash. Even trying to switch a Grass resist or special wall into Skymin is risky because you have the 80% chance to have your Special Defence turned to crap thanks to Serene Grace, which makes Skymin turn into the most deadly Flincher in the game because of the 60% chance of a Flinch from Air Slash. Skymin's ability to force out such a large amount of Pokes means it can easily run a SubSeed set, which it does amazingly because every Flinch from Air Slash means free recovery. Despite not being seen as much, Specs and Life Orb both bring lots of power to the table, Life Orb allowing Skymin to run through teams suprisingly easily, and Specs just being able to clean up so easily late game.
Inconsistent: This is the most bullshit ability ever made. Any Inconsistent user can switch in on something that can't do shit to it and Sub on the switch and start Protecting, hopefully getting Evasion and Speed boosts at first. Evasion boosts will potentially allow you to keep getting boosts and keep your Sub, while Speed boosts will allow you to Sub before your opponent can attack if its broken. Also coming along will be Special Defence and Defence boosts, along with Special Attack Boosts and Attack Boosts. After stalling for long enough, the Inconsistent user can start attacking, smashing though things with boosts to the attacking stat they are using, their Subs standing up to even strong super effective strikes with the boosts to their defences. The easiest way of handling besides making your whole team able to threaten them is to use Perish Song, but the list of viable users is rediclously small, being limited to Celebi and Politoed. Wobbuffet takes care of Politoed and Celebi if it lacks U-Turn, so it's a dubious option. It's possible to be completely immune to their moveset, but a list of those Pokes are few, and they can be PP Stalled if absolutely nescessary, or taken out if the user decides to run different moves than what is normally used. Changing the weather to Sandstorm or Hail is another option, making sure the Inconsistent user won't be getting Leftovers recovery and limiting the amount of Subs they will make, but forcing a player to do either of those just to make sure they have a chance of not losing to a very small group of Pokes is rediclous. Now, Inconsistent does lower a stat along with rasing one, but it raises one by +2 while only lowering one by -1 means your still getting a gain for each turn. I didn't include Hazing, Phazing, or the never miss moves because they can all fail, Hazers being KOed, Phazers missing, and the never miss moves generally not being strong enough to work.
Deoxys A: He needs to be gotten rid of as quickly as possible. He possess movepools and humongous attacking stats backed up with amazing Speed, ensuring that the only things taking him out are Priority or Scarfed Pokes, both of which are easy to notice and with some prediction, eliminate with the right move. Often times though, you can click Psycho Boost and watch the either the Poke thats currently in or the switch in very likely die. Even most resists can't take the move well, severely damaging them or OHKOing them. Infact, Scizor can be OHKOed with Psycho Boost+Extremespeed a large amount of the time with Stealth Rock in play. delving deeper into Extremespeed, it's also one of Deoxys' most important moves, stoping weakened Scarfers and Priority users from revenge killing you so easily. The only reason why either of these two would be considered easy to switch into is because people keep making the most obvious moves, and not taking any risks because of his frailness. If people would actually try and predict with Deoxys, he would be an absolute monster, and pretty much everyone would be saying to ban him.
Drizzle: Now, anyone who's faced me would think i'm only nominating Drizzle because I use Sandstorm. That's not true at all. If you look at all the other weathers and their abusers, you'll see that Rain has the advantage over all of them because of the amount of abusers and the power that comes along with them. Rain also has the advantage with the weather starter, being able to smash right through Sand and Sun with Water smashing through them. Hail has a bit of a advantage because of Abomasnow resisting Politoed's Water attacks, but falls to any using Choice Specs and Focus Blast. The absusers themselves really break it. I keep seeing people say that Nattorei will easily stop Rain teams, and frankly, I find that to be bullshit. Nattorei gets smashed by Kabutops Low Kick, Ludicolo uses Focus Blast, and Kingdra can 3HKO with Specs Hydro Pump. eventually, Nattorei will be killed, and than Rain will have a field day with most peoples only check to them gone. Manaphy can also stall out Nattorei with Calm Mind and Rest, eventually getting to +6/+6, and killing Nattorei and the rest of your team. For anyone who wants to ban them individually, why would you do that when banning the thing thats making them broken will result in less bans? It's just utterly absurd that people could still think that Rain could be okay at all this gen when you can spam it and get a good win streak. Oh, and for anyone saying that banning Drizzle will make Sand dominate, theres something called Suna and Hail, or mabye you should carry something to handle Sandstorm.
