Last year when chloe won miss clintz title, a new card was release. I think it will probably be the same thing so you won't have her for free (if I remember correctly, the only card the staff gave was gaia noel)
The same question was asked in this thread. Perhaps you can read it.
Q: Does the owner of Ms Clint City card get a duplicate in his/her collection?
or a new card appears on the market but the owner of the card does not get the duplicate?
A: Admin replied: Miss Clint City is a new card. For exemple, the owner of a card Chloe (R) owns Chloe (R) but not Miss Chloe (R).
When the Miss Clint City will be elected, you'll find this new card in the shop.
