Creature â Vampire Knight
At the beginning of each player's end step, Crimson Honor Guard deals 4 damage to that player unless they control a commander.
The player could control any playerâ€™s commander to satisfy Crimson Honor Guardâ€™s ability. If a player gains control of another playerâ€™s commander â€œuntil end of turn,â€ the player who gained control of it will still control that commander during the end step.
Crimson Honor Guardâ€™s last ability triggers at the beginning of each playerâ€™s end step whether that player controls a commander or not. Whether that player controls a commander is checked only as the ability resolves.
Crimson Honor Guard will deal 4 damage to you, too, if you donâ€™t control a commander.
