In any contest rank the goal is to win but how to win? Feed your Pokemon pokeblocks for the correct contest your entering Example: Tough contest you must feed sour pokeblocks to your Pokemon. Now if you feed them very good level pokeblocks and less feel pokeblocks you can go to slateport city and go in the Pokemon fan club show the gentleman your Pokemon and he will reward you with a yellow scarf, have your Pokemon hold this scarf and now teach your Pokemon tough moves Example: Waterfall is a tough move or tackle or take down. Finally use the tough moves in the contest and try your best to get the crowd goind for you and you will win.
