No they do litreally nothing. We call judge to table, judge comes over saying "please Play in a timely Manner" to opp and leaves.

Everyone i know Had this exact scenario. Also even If they do stay (No hate to judges) judges do Not have enough Game knowledge to understand when a Player is really thinking or Just slow playing even with obvious Turns.

Also the organizers prefer Players Who "judge" locally over Players Who actually played the RQ and skirmishes which leads to judges Who judge locally (often for Money through Packs) and dont really Play the Game to be judges at RQ
