Level Limit - Area B
① Change all Level 4 or higher monsters to Defense Position.
● Monsters can still be Summoned in Attack Position.
● Monsters can still change their Battle Positions. They just switch back to Defense immediately.
● If "Caius the Shadow Monarch" is Summoned, it's changed to Defense Position immediately.
After Caius' effect resolves, even if it banished this card, Caius will remain in Defense Position.
