During your opponent's turn: You can banish this card from your Graveyard; excavate the top card of your Deck, and if it's a Normal Trap Card, Set it directly from your Deck (this is a Quick Effect). Otherwise, send it to the Graveyard. A card Set by this effect can be activated during the turn it is Set. If this card is sent to the Graveyard: You can look at the top 3 cards of your Deck, then place them on the top of your Deck in any order. You can only use each effect of 'Absolute King Back Jack' once per turn.
