Weird gamebreaking bug! Anyone else? (Xbox 1)

I’m not able to use my cards in battle. When I LB to activate, it actually shows me the opponent’s cards, not mine, and of course I can’t activate my opponent’s cards. Which of course makes the game unplayable.

I’m level 317, so not likely to give up until I find a solution! (yes, I submitted a ticket, just wanted to know if anyone experienced this)

Halp!
