So I noticed today that my card percentage had gone down again, which means they added more cards. They had already added the Splitwater Coast cards quite some time ago, and now they've added an entire new zone's worth of cards. I wonder if we will be getting two zones next level cap increase, which hasn't happened in a long time. Could even be a new lower level zone like Coast of Opportunity. Or maybe they are just looking way, way ahead to the future.
If you have Yaclt you can see the cards under Unknown zone.
