Anyone else doing a battle frontier run before ORAS is released?

Just got arena and tower left for silver. My main team is Blaziken, Latios and Ludicolo. I use linoone for Pyramid and Skarmory for pyramid/pike to avoid random poison bullshit.

I also have an armaldo and claydol but they're shit. Planning on training up a salamence, flygon and metagross later. My latios has 31 in both special defense and speed so i think i got lucky, or does he always have 2 evs in 31?
