“Noble Knights” get a new toy to play with – and not one you may have expected.
LVAL-EN086
Gwenhwyfar, Queen of Noble Arms
LIGHT Spellcaster / Effect
Level 2 300/300
You can target 1 “Noble Knight” monster you control; equip this card from your hand or Graveyard to that target. You can only use this effect of “Gwenhwyfar, Queen of Noble Arms” once per turn. The equipped monster gains 300 ATK. Apply the appropriate effect, depending on the Attribute of the equipped monster.
●LIGHT: If the equipped monster would be destroyed by a card effect, you can destroy this card instead.
●DARK: If the equipped monster battles an opponent’s monster, at the start of the Damage Step: You can destroy that monster, then destroy this card.
A new “Noble Arms” card in the form of a monster. It acts like other “Noble Arms” cards in that you can equip it to a “Noble Knight” – where its then treated as an Equip Spell Card, thus unlocking the equipped card’s effects. It can even be equipped from your Graveyard, meaning your “Noble Knight” will be far less likely to ever be without an Equip.
