It's a Prosopocoilus inclinatus! (Mega Pinsir sweep)

[Kabuto Mushi]

Hey there! Currently trying my hand at the XY OU metagame for the first time. I have a team build here, but I know there are plenty of things that can be improved.

Basically, I'd like it to be a balanced offense team, with Pinsir and his shiny new mega stone bringing up the rear as an end-game sweeper. Bug/Flying is actually pretty decent typing, but if I can save him till the end I don't have to worry so much about his biggest weakness: Stealth Rock. Pinsir's set looks like this:

Pinsir @ Pinsirite
Ability: Moxie
EVs: 252 Atk / 252 Spd / 6 Def
Adamant Nature

• Swords Dance
• Quick Attack
• Return
• Earthquake

Flying and Ground get awesome coverage, hitting many threats for at least neutral damage. After a quick SD on a switch or a lucky Moxie boost, there isn't much this thing can't deal with in a single blow. Thanks to Aerialate boosting his Flying STAB to insane levels, Quick Attack hits with comparable power to Scizor's Bullet Punch. It's also useful for picking off weakened pokemon while still in normal-Pinsir form and nabbing your +1. Return is Pinsir's super strong nuke move... most if not all physical walls that take neutral damage from Flying are OHKO'd at +2. Earthquake rounds it out, taking down stuff like Heatran and Aegislash. Even with uninvested HP and defenses, MegaPinsir is bulky enough to shrug off a stiff priority move or two (Aegislash's Shadow Sneak for example).

So, I need a way to deal with the few pokemon that can counter this guy. A quick list right off the bat:

• Skarmory
• Talonflame (priority Brave Birds suck)
• Flying or Levitating Electrics (Rotom-W, Zapdos, Thundurus)
• Assorted super bulky Water/Ice/Ground/Steel types (Landorus-T, levitate Bronzong)

Ugh, that dumb washing machine everywhere these days. The rest of the team should be designed around taking out these threats as best as possible in order to let Pinsir do his job.
That first point is easily taken care of:

Magnezone @ Choice Specs
Ability: Magnet Pull
EVs: 252 SAtk / 252 HP / 6 Spe
Modest Nature

• Volt Switch
• Thunderbolt
• Flash Cannon
• Hidden Power [Fire]

A "textbook" answer to Skarmory problems, Magnezone. Not only can he easily trap and kill that metal bird, Zone can help fight off choice bulky waters, Ice types, and Fairies that might trouble Pinsir. Choice Specs and max HP are chosen to let it make use of it's nice resistances while hitting incredibly hard. Scizor trying to Bullet Punch Pinsir down early will get a nasty surprise in the way of HP Fire. A slow Volt Switch is also a great way to bring in Pinsir towards the end of the match with no damage. Flash Cannon has been upgraded from last gen: "Filler move" to "Fairy killer".

Next, I need something that can easily handle Talonflame, and also partners well with Magnezone:

Slowbro @ Leftovers
Ability: Regenerator
EVs: 252 Def / 252 HP / 4 SAtk
Bold Nature

• Slack Off
• Scald
• Thunder Wave
• Ice Beam

My Bro here can take even boosted Fire and Ice moves in his sleep, and doesn't mind getting punched in the face with a Fighting move to save Magnezone either. On a good day he can even take on MegaKangaskan and live to tell about it. Thunder Wave really makes this set, allowing him to slow down faster attackers for the also-quite-slow Magnezone. It also really helps Pinsir out if many of the opponents are slower, allowing him to use his more powerful moves without resorting to Quick Attack. Ice Beam nets the surprise KO on annoying Dragons, like 'Nite and 'Chomp. Scald is used over Surf for the extra Burn chance, which can be a saving grace against the aforementioned MegaKanga.

Pinsir is strong, but that doesn't mean he can't make use of entry hazards to turn 2HKOs onto OHKOs. I also still need a check against those pesky Rotom-W. A good counter would be a bulky Grass type that can do both of these things, while having good type synergy with the rest of the team.

Roserade @ Black Sludge
Ability: Natural Cure
EVs: 252 HP / 252 SpD / 6 Spe
Calm Nature

• Spikes
• Rest
• Leaf Storm
  
• Sludge Bomb

Roserade is great at laying spikes, usually coming in on a Water or Electric move and forcing the attacker out. It's a really great counter to Rotom-W especially, thanks to the fact that it can absorb Will-o-Wisp or Toxic for the rest of the team (Slowbro in particular wants to avoid that poison damage). Leaf Storm blasts bulky waters for great damage, and the SpA drop doesn't matter much when you are Resting up and switching next turn anyway for full health. Sludge Bomb is mostly filler, but it does get nice coverage on fairies and other Grass types looking to sponge Leaf Storm.

Looking at the team thus far, you notice how it's quite lopsided on the special attacking side. I wanted a strong physical attacker with typing and moves that would fit in well with the rest of the team. Enter Bandlax:

Snorlax @ Choice Band
Ability: Thick Fat
EVs: 252 HP / 252 Atk / 6 SpD
Adamant Nature

• Body Slam
  
• Pusuit
• Earthquake
  
• Self-Destruct

Here one of my favorite sets makes a return. Snorlax has the HP and defenses to tank hits from some of the best sweepers in the metagame and deal back bone crushing damage. Thick Fat is a great ability, providing a pseudo resistance to Fire and Ice, which basically my whole team greatly appreciates. Most people run Return, but personally I swear by Body Slam. I'd rather do 70% most of the time and a clean 2HKO sometimes (thanks to paralysis) than 80% all of the time. Pursuit traps and kills frail pokemon (psychics looking to take out Roserade, for example), and Earthquake grants coverage against Steels. Self-Destruct is for when Snorlax is on his last breath, or for if I need to take out a particularly troublesome pokemon to make way for Pinsir's sweep.

Finally, a pokemon to lay down Stealth Rock of my own and disrupt the opponent's lead pokemon.

Mamoswine @ Focus Sash
Ability: Thick Fat
EVs: 252 Atk / 252 Spe / 6 Def
Adamant nature

• Stealth Rock
  
• Earthquake
• Ice Shard
  
• Endeavor

I had a tough time choosing a pokemon for this spot, but I think Mamo does a decent job either putting up SR or messing with the opponent's momentum. Earthquake and Ice Shard work together to take out Focus Sash leads, and Endeavor makes him a huge threat when a revenge killer brings him down to 1 HP. Stealth Rock makes Pinsir's sweep that much easier, by severely injuring several Flying types that would give him trouble. Also if I can keep him alive, Ice Shard works wonders on KOing Landorus and Gliscor.

OK, so that's the team! Please suggest whatever you like for changes, and I'll test them out on Showdown. Thanks for helping!!

Could I bump this once? I put a lot of thought into it and nobody replied. It's a pretty fast board, huh?
