Overview: Serperior, the one starter that is perhaps hyped too much for its own good. Contrary is indeed one beastly ability, combined with leaf storm to abuse it. Too bad its dream world ability is yet to be released, and thus relegating the serpentine overlord down the tiers into RU. Although it's offensive presence is lackluster without contrary, it is still quite capable defensively and can function as a fast subseeder, the second fastest in RU. It also gets the new boosting move Coil, which helps it bolster its admittedly mediocre defenses and boost its attack, with leaf blade and dragon tail to augment its offensive options.

A bulkier but slower version of Sceptile. 113 speed is quite amazing in RU, and not many will be able to out-speed you without a scarf or a boost. Switch into something that can't hurt you, most likely a ground type, sub up in their face and start seeding. Dragon Tail is to force out stuff that you can't seed, leaf blade and giga drain for damage, and in giga drain's case, recovery. For the last slot you have a few options. Protect can help rack up even more seed damage/recovery, Dragon tail if you run leaf blade or giga drain, the new and improved 90 accuracy glare for unresisted paralysis, and toxic for even more residual damage.
Offensive Coil
Item: Leftovers/Life Orb
Nature: Careful
EVs: 244 HP / 12 Atk / 252 SpD
~Coil
~Leaf Blade
~Dragon Tail
~Substitute
Serperior has a great boosting move in the form of Coil which adds to his attack, defense, and even accuracy. And that defense boost is much needed as well, since Serperior will need to take at least one hit before he can reach +2, where his offensive presence can finally start to be felt. Leaf Blade is for STAB as usual, with high power and high crit ratio. Dragon tail to force out anything that you cannot hit for massive damage with leaf blade. Substitute is a must so that you can Dragon Tail things that threaten you without getting killed first.
Team Support
Item: Light Clay
Nature: Timid
EVs: 252 HP / 4 Def / 252 Spe
~Light Screen

Serperior is one of the fastest Dual Screener in RU, and its bulk helps it to get the job done. Not only does it set up screens, it also spreads a status effect of your choice (or even 2), seeds the opponent, or protect your team from status effects. Quite handy, isn't it? Also let's not forget that it's a complete taunt bait.
Other Options
lolGrowth with Sun Support and Hidden Power Fire and Return might be a little bit decent. Might. At least it does have neutral coverage this time.
