Individual Card FAQs
If you have 2 "Maurading Captains" on your side of the field, the opponent cannot attack any face-up Warrior-Type monsters you control. They can attack your Life Points directly if they control a monster with an effect that allows it (Such as "Rainbow Flower", "Inaba White Rabbit", or a Toon Monster). They could also attack a non-Warrior Type monster you control.
Your opponent can attack face-down monsters while you have "Maurading Captain" on the field, even if the face-down monster is Warrior-Type.
If you control "Maurading Captain" and a Warrior-Type monster equipped with "Ring of Magnetism", the opponent must attack the monster equipped with "Ring of Magnetism" if they choose to attack.
If you control 2 "Maurading Captains" and one of them is equipped with "Ring of Magnetism", your opponent cannot attack either one.
If you control "Patrician of Darkness", "Maurading Captain" and a Warrior-Type monster when your opponent attacks, you can use the effect of "Patrician of Darkness" to redirect the attack to "Patrician of Darkness" or "Maurading Captain" only. Not to the other Warrior-Type monster because it cannot be attacked.
The monster Special Summoned by the effect of "Maurading Captain" does NOT have to be a Warrior-Type monster.
If your opponent activates "Torrential Tribute" in response to the Summoning of "Maurading Captain" (by chaining to the Trigger Effect of "Marauding Captain"), all monsters on the field will be destroyed, and then you Special Summon for "Maurading Captain"'s effect. If they wait and activate "Torrential Tribute" in response to the Special Summoning of a monster for the effect of "Marauding Captain", then all monsters will be destroyed including the newly-Special Summoned monster.
Netrep Q&As
Q: If my opponent attacks "Marauding Captain" on my side of the field can I activate "Shift" and redirect the attack to another Warrior-Type monster? A: The other monster is not a legal target for "Shift" in this case, because "Marauding Captain" will not allow it to be attacked. Curtis Schultz, 12/20/2003
