low opl

Your question looks incomplete — "low OPL" alone isn't a scenario. Could you give me the full situation?

For reference: Low (Casual) OPL is the most relaxed organized play level (TR 205.2) — deviations from rules/policy are treated with lower penalties and a focus on education and sportsmanship. Once you describe what happened (e.g., "opponent forgot to shuffle their trash back in between games"), I can give you the exact ruling.
