Ok, my thoughts:
I already told you some stuff:
- Change Choice Scarf Jolteon for Choice Scarf Latios, as scarfed Latios has more special attack, can switch into more attacks than Jolteon, and has better move coverage and better move options. If you really want to use Jolteon, then give it either Life Orb (recommended) or Choice specs.
- Give Metagross 252 HP, 252 Atk EVs with an Adamant nature. 252 HP EVs gives it good all around defense, and with 252 Atk EVs and the Adamant nature Metagross gets over 400 attack, which is strong by any standard.
- Give Infernape Iron Fist instead of Blaze, as Iron fist boosts the power of Thunderpunch always, while Blaze only boosts the power of Flare Blitz when Infernape's HP is down. Also, I would change Infernape's item, most likely to the Life Orb, as Flare Blitz recoil, hazard damage, and weather damage will all negate Focus Sash. Even if you always use Infenrape in the lead slot, Focus Sash isn't the best item, especially paired with Flare Blitz.
