Welcome to the sleeper hit of the 5th Generation: the Rotation Battle! With 12 moves to consider at a time (13 counting switching), Rotation is a unique mode reliant even more on chance management and team synergy. Without further shameless commercial ado, I present a specially-formulated GBU Rotation Battle team. Those who know me shall slap me because this team is almost Bug-free.
Sprites aren't available at the moment but I'd like to get them up soon.
Thundurus @ Focus Sash
Rash
252 SpA/252 Spe/6 Def
Thunder Wave
Taunt
Thunderbolt
Grass Knot
This is indeed a Rash Thundurus. Judging by the fact that I totally forgot that I should probably try for a good nature on the runner this time, I'm fairly pleased with it.
That aside, Thundurus composes one half of my Thunder Wave duo. He's not usually my lead (as little as that matters in Rotation), but heads off the team here as an introduction to the theme. I'm experimenting with the Rotation equivalent of Parashuffling, in that I attempt to cripple as many of the opponent's crucial threats as possible to make way for a variety of slow, powerful attackers or ease setting up for a faster sweeper. Thunder Wave is a given, and the priority makes Thundurus my first choice at neutering Scarf Pokemon and things like Terrakion or Latios which could otherwise cause heavy damage to the team. Taunt has proved a complete success, shutting down status-lovers such as Dusclops, Sableye, Breloom, and Quagsire. Thunderbolt and Grass Knot miss out on a lot of type coverage, but deal with Water- and especially Ground-types that would otherwise be dangerous.
Regigigas @ Leftovers
Relaxed
252 HP/204 Def/54 SpD
Thunder Wave
Knock Off
Return
Confuse Ray
Laugh all you want, Relaxed isn't optimal either. He's from Pearl when I was a bit less than competitive in my Pokemon.
Gigas is a beautifully bulky complement to Thundurus, and often is enough to get the Paralysis job done on his own. Capable of surviving nearly any unboosted attack, Regigigas is often my paradoxical Rotate-in on Lucario, Tyranitar, Dragonite, weather sweepers, and Rotom. Knock Off relieves the opponent's mons of their Leftovers, Choice items, Life Orbs, or (gasp!) Lum Berries. Return is a solid STAB attack which, off an uninvested base 160 Attack, becomes dangerously powerful after Slow Start wears off. Confuse Ray comes into play when I'm feeling desperate, and more often than not seems to let me down!
Nidoking @ Life Orb
Modest
252 SpA/252 Spe/6 HP
Earth Power
Ice Beam
Flamethrower
Thunderbolt
A Fighting and Rock resist with a Toxic immunity, mediocre speed, and lethal special Force? A necessity for this team! Nidoking often hangs out in the back of the field pretending to be Scarfed, coming in when the immediate dangers are Paralyzed and the opponent's field can all hit super-effectively. Which is actually quite often. Earth Power is a mighty STAB move, Ice Beam deals with some of the metagame's most popular Pokemon (like opposing Grounds), Flamethrower dispatches Bug-Steels and Ferrothorn, and Thunderbolt slams Water-types like Jellicent and Vaporeon.
Aggron @ Air Balloon
Adamant
252 HP/252 Atk/6 Spe
Substitute
Head Smash
Focus Punch
Ice Punch
Forget Blaziken. Set aside Drizzle and Swift Swim. The Air Balloon may be one of the most broken things in the Rotation Battle metagame. The message "Aggron is holding an Air Balloon" doesn't appear at all I send her out in the back of the 3 leads! This allows her to effortlessly torture Gliscor, Garchomp, Excadrill, and Dragonite by setting up in their faces and launching an Ice Punch or Head Smash back at them. After so many gleeful experiences like that, I never want to leave home without my Aggron.
Salamence @ Lum Berry
Adamant
252 Atk/252 Spe/6 SpD
Dragon Dance
Outrage
Earthquake
Fire Blast
Salamence helps to disguise the stallish nature of my team on the Team Preview as well as be my insurance against any quick mon I didn't Paralyze. Getting a free DD is easy with the Fighting, Ground, and Water moves flying at Nidoking, Aggron, and Regigigas. After that, I keep him in the back until the team is ready to get swept. Outrage + Lum Berry is pretty cool if I don't sacrifice the Berry for a Dragon Dance. EQ is obvious, and Fire Blast with an Adamant nature is from when I used Fire Fang before I found out it was bad.
EDIT: As of late I've replaced Hydreigon with this:
Scizor @ White Herb
Adamant
252 Atk/252 Spe/4 Def
Swords Dance
Superpower
Bullet Punch
Bug Bite
Scizor provides the priority I realized I needed so badly despite the paralysis. His Ice resistance gives him opportunities to SD against opponents trying to nail Thundurus or Salamence, and Mence compliments Scizor by taking the ever-obvious Fire moves. Because of the increased impracticality of switching in Rotation, White Herb restores my stats if I have to take out a Steel with a somewhat surprising Superpower. The fast spread is equally surprising, but I've often considered changing him (or training a new one) to a SpD version.
-------------------------------------------------------------------------------------------------------------------------------
Hydreigon @ Dragon Gem
Modest
252 SpA/196 Spe/62 HP
Draco Meteor
Dragon Pulse
Surf
Flamethrower
The EV spread is a relic from when it was popular.
This Hydreigon alternates between Scarf, Specs, and this, and she's currently the object of contention on this team. As much as I like GemDM, another Flamethrower, good bulk, and a Psychic immunity, she feels like a combination of Nidoking and Salamence. I have a couple ideas in case I decide to replace her, but for now she's performing flawlessly and has saved me a difficult game or two.
