If you control “King’s Sarcophagus”, you can Special Summon this card (from your GY). You can only Special Summon “Hapi, Guidance of Horus” once per turn this way. If another card(s) you control leaves the field by an opponent’s card effect while you control this monster: You can target 2 cards that are banished and/or in the GYs; either add both to their owners’ hand or shuffle both into the Deck. You can only use this effect of “Hapi, Guidance of Horus” once per turn.
