I am writing to report a serious bug that has made the game unplayable for me. In Best of One matches, when I click "Play" and enter a game, everything proceeds normally until the opening hand phase. At that point, I am prompted to choose whether to keep my hand or take a mulligan — but the option to “Keep” my hand does not appear on screen.

As a result, the only option available is to mulligan. This continues until I have no cards left in hand, causing an automatic loss. This issue has occurred six times already, and due to the frustration and inability to play normally, I decided to stop playing altogether.

I’ve ensured my game client is fully updated, and I’ve tried restarting both the game and my device, but the issue persists.

Please investigate this bug.
