Put any pokemon your want at level 100 in the daycare. Then go to a mud slide with a bike and tape down the up button so you go up and down! Grab your sp charger plug it into the wall and the sp and leave it on over night! By the morning go back to the daycare and your pokemon will have gained many levels! My Gordon was at level 45 and when i woke up he gained 14 levels! And my numel at level 12 was at level 41.
