As the sixth fastest Pokemon in VGC 2011 with access to Safeguard, dual screens, and other useful moves, Serperior would seem to have a niche in the VGC 2011 metagame. However, Prankster users make Serperior's superb Speed almost useless, and with no impressive attacking stats to fall back on to make good use of its Speed, Serperior often finds itself a dead weight once it's finished setting up or is Taunted. Overall, Serperior isn’t too threatening or helpful, but still does a great job of setting up screens and has just enough other options to get by.

Name Item Nature

Dual Screens

Light Clay / Mental Herb Jolly / Timid
Moveset EVs
~ Light Screen
~ Reflect
~ Glare / Safeguard / Taunt
~ Leaf Blade / Leaf Storm
252 HP / 4 Atk / 252 Spe

Thanks to its fantastic Speed, Serperior sets up screens before most Pokemon can attack, making it a great dual screen user. After setting up screens, Serperior can proceed to use Glare or Taunt on your opponent's Pokemon, making them more vulnerable to attacks. Alternatively, it can set up Safeguard, which is a great move to protect your team from Amoonguss and other status abusers. To show how helpful screens are, assuming both Archeops and Tornadus run max Attack, a neutral nature, and Reflect is up, Tornadus will never KO Serperior with Flying Gem boosted Acrobatics without a critical hit, while Archeops only has a 7% chance to KO Serperior. Leaf Blade is a great move with its high critical hit rate, and has the added bonus of hitting Jellicent on its softer physical side for super effective damage. Leaf Storm, used twice, will outdamage Leaf Blade, and Serperior may not be attacking that often anyway.

Calm Mind

Chesto Berry / Life Orb Timid
Moveset EVs
~ Calm Mind
~ Giga Drain
~ Hidden Power Ice / Taunt
~ Rest / Protect
252 HP / 4 Def / 252 Spe

With good defenses and Speed, Serperior is a noteworthy candidate for Calm Mind, needing little help from its teammates to set up. After a Calm Mind or two, Serperior's offensive abilities improve significantly, and enable it to bring down most Pokemon with Giga Drain and Hidden Power. Unlike Lilligant, Virizion, and Volcarona, Serperior initially outspeeds crucial threats such as Tornadus and Terrakion and doesn't have a crippling 4x weakness to Flying- or Rock-type moves. Hidden Power helps make up for Serperior's poor coverage, hitting its would-be counters for super effective damage. Rest plus Chesto Berry is one instant recovery, while Life Orb gives Serperior more power but reduces its survivability.

Other Options

A Swords Dance or Coil set could work, but Serperior's physical movepool is very lacking, with nothing of note outside of Leaf Blade, Dragon Tail, and Return. Serperior can set up Sunny Day and gets Growth, but again, it doesn't have much to work with. A SubSeed set could work but Whimsicott probably does it better, and SubSeed isn't as effective in doubles as it is in singles to begin with. Double Team is not banned in VGC, and Serperior is arguably one of the fastest and bulkiest users. After a few Double Teams, the Calm Mind set becomes hard to stop.

Checks and Counters

Whimsicott is annoying with Encore, and the other two Prankster users can carry Taunt, which seriously impedes Serperior from doing anything useful, but must watch for Serperior carrying Mental Herb. Most Flying-types carry Acrobatics with a Flying Gem, and can kill Serperior without Reflect up. Other good checks include Chandelure, Darmanitan, and any other Pokemon that resists Serperior's attacks and can get through its bulk. Putting aside the threat of Serperior's Taunt and Safeguard, Amoonguss's bulk and typing make it hard for Serperior to do anything noteworthy to the giant mushroom. Bouffalant and Sawsbuck are hard counters with their Sap Sipper ability, raising their Attack stats each time they're hit by a Grass-type attack, while shrugging off anything else Serperior throws at them. Sawsbuck should be a bit wary of Hidden Power, though.
