There are two sets I'd like to share:
Simipour @ Choice Scarf
Trait: Torrent
EVs: 252 Spd / 252 SAtk / 4 HP
Modest Nature
- Hydro Pump / Surf
- Ice Beam
- Grass Knot
- Focus Blast / Surf
An effective revenge-killer, letting it outspeed many threats. It's the on-site moveset, so I don't have much to say here.
Simipour @ Salac Berry / Petaya Berry
Trait: Torrent
EVs: 252 SAtk / 252 Spd / 4 HP
Modest Nature
- Substitute
- Surf
- Ice Beam
- Grass Knot
SubSalac Simipour is pretty good because it has 3 more spots left for STAB + Coverage, and it's 3 coverage move covers pretty much the entire tier. The strategy with this is pretty basic: Substitute until you get to Torrent + Salac / Petaya Berry range, and fire off insanely high powered STAB Surfs. Ice Beam and Grass Knot let you hit Grass and Water-types, respectively. Salac Berry is useful if you need Speed, although if you want to hit even more harder, Petaya Berry is the best option.
