I think that you should keep HP Grass if you're using this as a lead, mainly for Swampert. If you choose not to, use Flamethrower.Good point. I feel stupid now.
Eh, I thought it did resist water. In any case, I'll try running it with a different move in that slot, here in a little while.

Anyways, I've been thinking (no, I can't test it cause of my cursed Shoddy) of the following moveset. If someone wants to test it out for me...
Cyclohm @ Salac Berry
Timid/Modest Nature- Shield Dust
176 HP/ 144 Spe/ 188 Spa
Substitute
Charge Beam/Thunderbolt
Dragon Pulse
Surf/Flamethrower
Yeah, its a Subberry strategy, but I can use three attacks if I choose to have Charge Beam, which has a high chance of boosting Special Attack. I chose Salac to make up for the low Speed.
