Xavier, Closing Overlord

Section check (Just a Second! At the beginning of
each opponents end step, if their board isn't tidy,
Xavior deals damage equal to his power to them.)
Whenever Xavior deals damage to a player, give
them a verbal warning of what they are doing
wrong. If this is their second time, give them a
written warning instead. If this is their third time,
fire them from the game. (They lose the game)
His favourite Pink Floyd song is Bike.
