Could you tell me your PC specs and which linux distro you’re using? Also what mode and deck you’re using (if duel)! I want to try to reproduce the issue.
So I just tested on my steam deck and it works just fine. Could you please post your player log on a pastebin or something? It should be located in ~/.config/unity3d/Flaming Torch Games/Fairtravel Battle/Player.log
To clarify: tutorial work without problem. In duel mode and others, it pass through starting muligan phase so i can play first turn if i am first. Tested LAN play too, no problem here if i dont add any bots.
