Hello, my first RMT didn't really generate any buzz, but I ended up changing my team and this is what I'm currently running.
Sableye with Leftovers
Ability: Prankster
Nature: Calm
EVs: 252 HP, 120 Defense, 136 Special Defense
Moveset:
Taunt
Confuse Ray
Will-O-Wisp
Recover
Sableye is the most annoying and infuriating Pokemon I've ever encountered, and I finally gave into peer pressure and put her on my team. I generally use Sableye as my opener to immediatly put pressure on my opponent with Taunt (if they're the type of pokemon to set up), or Will-O-Wisp (if they're the type to attack), and I follow up with a Confuse Ray to be a huge nuisance. I know not having an attack move leaves me open as Taunt bait, but I've yet to get taunted by a fellow prankster.
I originally ran Crocune, but it felt ineffective and it sometimes let other Pokemon set up if Sleep Talk screwed me. Suicune is my current special sweeper, and since it's bulky, it can take some punishment as well. Surf is primary STAB damaging move, Ice Beam lets me deal with Grass Pokemon switching in on me, and Hidden Power Electric is for fellow water types trying to stall. I'm still trying to decide whether or not I should keep her on, and I'm considering replacing Suicune with Chandelure.
Hitmontop is primarily used to clear entry hazards for a Ninjask set up, but it can also finish low health Pokemon with Fake Out and Mach Punch. Toxic also gives me a good way to inflict status and make sure a sweeper doesn't stay out for too long (assuming it doesn't destroy me in 1 hit). Hitmontop doesn't do anything against ghosts though, so I'm considering switching Fake Out for Sucker Punch,
Mienshao with Choice Scarf
Ability: Regenerator
Nature: Naive
EVs: 252 Attack, 252 Speed, 4 HP
Moveset:
U-Turn
Hi Jump Kick
Stone Edge
Hidden Power (Ice)
Mienshao functions as my revenge killer, and a solid late game sweeper. Her move set is pretty standard (I think). U-Turn lets me scout easily (and lets me get health with regenerator), Hi Jump Kick does absurd damage with STAB and lets me OHKO A LOT of Pokemon, Stone Edge lets me destroy Crobat and Zapdos who are both extremely popular, and finally Hidden Power Ice is pretty much just for Gligar who'd wall me otherwise.
Ninjask with Focus Sash
Ability: Speed Boost
Nature: Adamant
EVs: 252 Attack, 252 Speed, 4 HP
Moveset:
Swords Dance
Protect
Baton Pass
X-Scissor
Ninjask can set up some devastating sweeps by passing along attack and speed boosts. Since Ninjask is so frail, Focus Sash allows me to get 1 Swords Dance off for sure (unless I get hit my a multi-hit move), and comboed with Protect gives me +2 speed. X-Scissor makes sure I'm not dead weight if I get taunted, and if I got off a Swords Dance, it usually results in some kills.
Scrafty with Lum Berry
Ability: Moxie
Nature: Adamant
EVs: 252 Attack, 252 HP, 4 Speed
Moveset:
Drain Punch
Ice Punch
Crunch
Zen Headbutt
Scrafty is my primary choice for Baton Pass, and given its natural bulk, it can usually take a hit switching in. Since Scrafty has horrible base speed, I don't bother with Speed EVs, and instead try and make sure that I can survive the switch in. Assuming I have +2 speed and +2 attack, it's pretty much game over for the enemy. I think this moveset gives me solid coverage, and Lum Berry makes sure that a Will-O-Wisp/Confuse Ray isn't going to be the end of me.
