Hrm... well i need a 'Mence counter/ check, and i was told Mamoswine was good for that
Mamoswine can check Salamence because it easily OHKO's it with CB Ice Shard. There is no real counter for Salamence since Swampert is one of the few things that can take a +1 Outrage and Earthquake but it can't take a Draco Meteor. I've found that Bronzong works pretty well against any Salamence, but it usually has to Explode to take it out. I've considered trying a Bronzong with Trick and Lagging Tail to cripple it and then send in something on the predicted Fire Blast and KO it that way, but Shoddy doesn't have Lagging Tail.
Basically, anything with 100 or more Base Speed, holding a Choice Scarf and having either an Ice move or a STAB Dragon move can check Salamence. Also, be sure to put SR up so it can't switch in as often.
