Bodyguard
The Bodyguard keyword represents two abilities.
The first of these is a static ability that functions while the character is being played. This ability means “This character may enter play with the exerted state rather than the ready state.”
The second is a static ability that creates a challenging limiter. This ability means “If an opponent would choose one of your characters to challenge, they must choose this character or another character with Bodyguard if able.”
