Noble Arms

"Noble Arms", known as "Holy Sword" ( Seiken) in Japanese version, is an archetype of Equip Spell Cards that was introduced in Return of the Duelist. It is based around the tales of the Knights of the Round Table and supports the "Noble Knight" archetype. Its first support was introduced in Abyss Rising with the release of "Ignoble Knight of Black Laundsallyn". They all (with the exception of Excaliburn) share following common effects:
 * You can only control one copy of the card face-up.
 * Equip only to a Warrior-Type monster.
 * If this face-up card on the field is destroyed and sent to the Graveyard: You can target 1 face-up Warrior-Type "Noble Knight" monster you control; equip this card to that target.

All cards in this archetype, save for Noble Arms - Excaliburn, have artworks that depict swords embedded in stones, a reference to the Arthurian legend of the Sword in the Stone.
