When I selected Brann Bronzebeard as my deck in Twist, the game told me that the deck was incomplete, and asked if I wanted it to be auto-completed. I hit “yes”, and it gave me a deck full of random cards.
The actual deck I use in game is still normal, but even after completing a game, it still shows the same deck of random cards on the “choose your deck” screen.
This is not the first time I’ve used the Brann deck, or even the first time on this device. I’m on a Windows 10 Pro OS.
