The standard Empoleon strategy, as applied to Moltres. This seems to do best early-game, or as a lead to avoid Stealth Rocks, but you will get some surprising power out of it. Substitute first, as with a lead, hoping your opponent sets up in some form. Then pull off the Agility. From there you're pretty much set already. Sub down to pinch health in order to activate Petaya, giving Moltres' already good SpA a much desired boost. From there, it's STAB all the way. Fire/Flying begets some surprisingly good coverage, and if there's something that can't be OHKO'd you always have a 30% chance of flinch from Air Slash.
