Re: fastest way to level up with priority moves[Rattata/Marill etc.]
<t>Another good method is using a pokemon with thunder wave and false swipe. You dont need a priority move then (sometimes will fail, cause to low level or to fast opponent poke). Give the leading pokemon black sludge and paralyse the opponent pokes, then you need to die :). I have a Bisharp, which I use for this technique.</t>
