Just like a lot of the gen 1 Pokemon, this guy is also a classic. Anyways allow me to show you an awesome physical moveset that will obliterate your opponent's Pokemon.
Item: Choice band.
Flare blitz: Does lots of damage at the cost of some hp.
Wild charge: A powerful physical electric attack that costs some hp You don't have to worry about those worthless water types anymore ;D.
Dig: Deals with rock type Pokemon.
Extremespeed or outrage: Extremespeed is a powerful move that most of the time lets you attack first. Outrage is even more powerful but you get confused after using it and it isn't a priority move.
Strategy: Choice band will allow your attack stat to be boosted however you can only use one move. (unless you switch out.)
