Roselia, Rhyperior and weavile!

Mamoswine is the best Ice attacker by far and is a top level Ground attacker.

Roserade is easily the best Poison attacker and probably the best Grass attacker as well.

Rhyperior is really, really good at Rock or Ground attacking.

Electivire is a great Electric attacker with Wild Charge.

Those are your best bets.
