If anyone gets what these are from, I'll be really happy.
Legendary Headband #1
Equip Spell
This card can only be equipped to a "Six Samurai" monster or a monster has "ninja" in it's name, and has battled on a previous turn. The monster equipped with this card is unaffected by spell and trap cards, and cannot be chosen as the target of a battle, unless the attacking monster is equipped with "Legendary Headband #2". If the equipped monster is destroyed, equip this card to the monster that destroyed it.
Legendary Headband #2
Equip Spell
This card is unaffected by the effects of cards that destroy spell or trap cards. During each of your battle phases, you must attack with the equipped monster. If the equipped monster is destroyed by battle, equip this card to the monster that destroyed it. If the equipped monster is destroyed by an effect, this card is moved to the monster with the highest attack on the field. If a monster is equipped with "Legendary Headband #1" and "Legendary Headband #2," increase the equipped monster's attack by 3000.
Just toying around with it. Still working out kinks and wording. Rough drafts if you will.
