What you think,

*Waits for Professor Oak to rate

The team was made by Marik.

It pwns.

End of story.

Raikou is vulnerable to Swampert and Duggy.
Gengar owns Blissey, but may struggle against Flygon and Salamence.
Pert is Pert. Repeated Special batterings hurt in general, but a Torrent Boosted Hydro Pump will hurt. I'm looking at Vappy for main counter.
STalk Regice. Pwns. May struggle against Calm-Kou/Cune/Entei, but will last for an Ice Age (lol)
Skarm gets pwned by anything faster with Taunt. DD-Taunt-Dos/Tar pwns it completely. Still, lasts for a while, and will survive a Modest Maggy's Thunderbolt.
HP Rock prevents misses ruining the sweep, and has Base 105 power after STAB. Ground/Rock has sexy coverage, Double Edge pwns bulky waters and anything that resists both Ground and Rock such as Breloom. I prefer the lack of suicide with Return, but that's just me.
