Card Rulings:Heroic Challenger - Extra Sword

OCG Rulings

 * If two copies of "Heroic Challenger Extra Sword" are used as Xyz Materials for a single Xyz Summon, when that Xyz Summon is successful, the effects of both copies of "Heroic Challenger Extra Sword" that increase the ATK by 1000 will activate in a chain. (As for the end result, that Xyz Monster will gain 2000 ATK).


 * If an Xyz Summon is performed using "Heroic Challenger Extra Sword" as an Xyz Material, and the Xyz Monster that gained 1000 ATK is affected by "Skill Drain", so that the effect of gaining 1000 ATK upon its Xyz Summon is negated, the ATK of that Xyz Monster returns to its original ATK value. Also, even if the effect of "Skill Drain" stops being applied, the effect that increases ATK upon the Xyz Summon of that monster is not applied once again, and its ATK is not increased again.
