Neither player has to pay Life Points during the Standby Phase for "Archfiend" monsters. Each time a player's "Archfiend" monster(s) is destroyed and sent to the Graveyard, except by battle, that player can add 1 "Archfiend" monster from their Deck to their hand that is a lower Level than the destroyed card.
