Alright, then I suppose a place to start would be with Mamoswine or something:
-Mamoswine w/Life Orb
Nature: Naive/Hasty
Ability: Thick Fat
EVs: 240 Attack, 252 Speed, 16 Sp.Defense
Moves: Earthquake, Ice Shard, Icicle Crash/Icicle Spear, Freeze Dry
Mamo makes for a good check to Salamence and Garchomp (because Ice Shard), who're commonly used. Earthquake is also useful against Steel types which also tend to be common. Ground/Ice is a nice offensive typing, really, and having an Electric immunity is good too.
