bring your luxray to the 40s
try getting a quagsire, his pre evo can be found on azurine island
it's a double battle and the key to win it is combos :
you mentioned an emolga, he's very good you can do a fakeout nuzzle combo then spam acrobatics
also earthquake quagsire - emolga combo is very very devestating
plus see if you can get an arcanine - it reks that dragalge pretty ez with outrage
should consider this, gl
