If yur lookin to raise a pokemon easy then this glitch is for u. Outside of lilycove city where you enter there is a girl cool trainer. the first time you battle her she will say "my goal is to beat five trainers a day. guess what ur number 5". Battle and defeat her! When you beat the pokemon leagu go to her again but this time she will say "My goal is to beat 10 trainers a day. your number 10" Give the pokemon you want to raise exp.share and let it battle, her pokemon are:
lvl.41 spinda
lvl.41 exploud
lvl.41 slacking
note: every time you beat the pokemon league and she will battle you every time you beat them!!!!!
