You get nothing.
five stars
You have to look for them in Pokemon Diamond. you have to look around the corner of the shop.
5 stars
Here's how to get five stars on your Trainer Card in Pokemon Diamond. I don't believe you have to do these things in order, but you have to do them all to get all five. Good luck: One Star - Blue Card: Beat the Pokemon League (Elite Four and Champion) once. Two Stars - Bronze Card: Beat all Pokemon Contest categories (Cute, Smart, etc.) at the Master Rank level once. Three Stars - Silver Card: Play the Underground Capture the Flag Minigame with your friends once. Four Stars - Gold Card: Capture all Pokemon in the National Pokedex. Five Stars - Black Card: Beat the Battle Tower 100 times in a row once. Hope I helped.
If you have Deoxys with you, it changes forme.
I think you have to beat the Pokemon Elite five times.
up to lv. 60

in about five months

From 9:00 to 23:00.
