Latios for my VGC team

[GiMYz]

I've used for a few days a SashLatios and it worked.. well i had a issue with Terrakion and M-Venusaur and instead of using a Scarf Gardevoir i've decided to try Latios.

Latios @ Focus Sash
Ability: Levitate
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
- Psychic (because Psyshock doesn't have a 100% chance to OHKO Terrakion without a Life Orb)
- Ice Beam (OHKO on Land-T, M-Mence, Garchomp)
- Tailwind
- Reflect (i was switching between Reflect and Protect in the last days, but Draco Meteor, Helping Hand, Thunder Wave/Icy Wind and Energy Ball are all viable if the team needs any of these. )
