Removing all cards in your hand and your side of the field from play is a cost to activate “Card of Sanctity”. If you have no other cards except for “Card of Sanctity”, you cannot activate it. You must have at least 1 other card on your side of the field or in your hand.
You can chain “Null and Void” to “Card of Sanctity”.
