My opponent was at 2 life they used lighting helix on my creature with finale it drains 2. They lost two life then gained 4 life. The game recognized they had hit 0 and called me the Victor with the victory screen. My opponents naihiri also said she won. Then when I got back to the main screen I got deducted points as if I lost when I won. Not sure if they bugged the game on purpose to get a win.
