Yeahl was being really stupid, think l need to refresh my mind all i did was continue where i left off havn't played pokemon games in a while and been breeding trading, the thing i was trying to remember a move Salamence knew that was super effective against another Salamence, and most all my other poekmon are weak to ground moves so i think im rebuilding my whole team now, and maybe restart EV train them all
I'm sure you don't want my advice, but Dragonbreath and Fly on Salamence is a big nono. Also Bullet Punch and Pursuit on Scizor would have would have killed Azelf when he switched out, and killed Salamence when he was on such low HP.
