About This File
This page holds a bunch of wc6full that were either test cards, unused cards, or cards that were in use but were not officially announced, found on the mystery gift servers for Gen 7.
Beacon Test Card
As far as I can tell, this test card started operations on 23rd March, 2017.
Inferring from it's server title, it was probably to double check that the wireless beacon was functioning as intended.
