I am in the Silver League III league and played approximately 45 games last week to move from Bronze to Silver. I looked at my profile stats this morning and it says I’d only played 9 games in duels. So I played a no move game (which is my go to preferred game to play in duels) and then looked at my stats right after and it remained at 9. So I then played a move duel and immediately after looked at my stats again and it did change to 10. So it looks like only move duels are counting, not no move.
