First of all you need 2 Heart Scales, which are found on the most wild Luvdiscs. Then capture a wild Medicham at Victory Road. Catch it and put it in your party, then go to Fallabor Town, go in the Move Tutors house and re-learn Ice Punch and: Fire Punch= Beauty Thunder Punch= Cool
Then enter a contest and use Ice Punch as first then the next turn use the other move, it wil result in a 8 heart combo! Plus 1 or even 6 for teh audience. This wil result in easy victories!
