I think it would be a good idea to use a Camerupt like this:
Camerupt @ Air Balloon
Ability: Solid Rock
EVs: 248 HP / 8 Atk / 252 SpA
Quiet Nature
- Earthquake
- Eruption
- Flamethrower
- Hidden Power [Electric]
With its ability solid rock, supereffective moves wont work as well against it. Its air balloon would keep it away from dangerous moves like earthquake and such.
Its good for protecting blastoise against supereffective grass-types.
