How do you get into the ribbon syndicate on Pokemon diamond?

If u have to win contests, what r good pokemon to useHow do you get into the ribbon syndicate on Pokemon diamond?
After seeing some of the other answers for this question, i knew i had to answer it correctly. I have entered the ribbon syndicate myself due to the fact i have the game and the guide.

This is how to do it

Get 10 ribbons on 1 Pokemon. They cannot be spread around your team. It must be just 1 Pokemon (i used my Rampardos).

You can get ribbons from winning contests, but that is very hard. Here are some other ribbons that might help:

Footstep Ribbon - make your pokemon happy

Effort Ribbon - make you pokemon powerful and use it a lot

Classic Ribbon - this comes on an event pokemon. If you get an event pokemon try giving that one lots of ribbons. That would mean you would only need 9 more instead of 10.

Hall of fame ribbon - if you defeat the elite four, you pokemon who helped you win the elite four gets a ribbon.

Hoeen hall of fame ribbon - if you pal park a ribbon collecting pokemon, if that pokemon had a hoenn elite four ribbon, that contributes to the 10 ribbons.

Hope i could help!
The Ribbon Syndicate is a building located in the Resort Area of the Battle Zone. It is difficult to miss with its large size and giant decorative ribbon over the doorway. A trainer must have at least 10 different kinds of Ribbons spread among their current Pok茅mon party to gain access to the building.How do you get into the ribbon syndicate on Pokemon diamond?
You need to fulfill one of two requirements



1: Win a master rank contest



2: Have 15 or more ribbons





Having either one will work. Once you get in you can go upstairs to give one of your pokemon a spa treatment that will raise its happiness an entire level.
