Is there an exchange programme if members want to change from one character to another?
There is no exchange programme. Each Aleta Adventure card is a limited-edition, serialised collectible permanently retired once sold out. Cards cannot be swapped, exchanged or reissued in a different character design.
If you would like a different character, you may apply for a new card when that character’s release is available, subject to account card limits. See FAQ 2.06 for details.
