And it's not like electrics have access to moves like Surf. You basically have to breed in moves like Ice Fang, hope they can learn Grass Knot, or switch to a different Pokémon altogether.

[And even then, dual typing might nullify their weaknesses. With Pokémon like Swampert, grass becomes a necessity.]

Honestly, I can see why Earthquake's so hard to come by. You could set up a whole team with the move and steamroll everything... not to mention what you're dealing with right now. Are they still at it?
