You may rest a recovered "Excalibur" you control rather than pay this card's cost.
Enter ⇒ Reveal cards from the top of your deck until you reveal a Knight of the Round Table. Put that card into the field and the rest on the bottom of your deck in a random order.
Whenever a Knight of the Round Table is put into a graveyard from the field ⇒ You may return this card to its owner's hand.
