My Azelf was Focus Sash with Explosion. The first game weakening Tornadus wasn't necessary to win, and I didn't use Scrafty for the rest of the game after Hurricane missed the first time. It didn't matter that Hydro Pump missed on Flygon either since you didn't have SR and Azelf was at 100% (252 Atk Azelf Explosion vs. 4 HP / 0 Def Kingdra: 277-326 (95.18 - 112.02%) -- 68.75% chance to OHKO).
