One of the main reasons why I stopped accessing TCG One was the lack of updates and addition of new collections. In that time, two collections were released, but we never saw them on the platform. Why?
Cuz all they care about is old formats
devs have all been busy with work and school
Now evolving skies available in collection, still can’t choose EVS card in quickplay deck
TCG One is a community and volunteer run site. New sets take time and effort to implement and can often bring new mechanics that may have to be accounted for within the pre-existing sets.
As card contribution is open-sourced, anyone including yourself is more than welcome to help contribute by adding any missing sets.
We are always looking for volunteers!
Hope that helps
