Prices from YGOPRODeck / TCGplayer, refreshed 9 hours ago. Each is that printing’s own market price, which is why they differ from the single market price beside the card above — that one is what every deck cost on this site is worked out from. We have no price for 1 of these, shown as “—” rather than as zero. Buy links go to TCGplayer through YGOPRODeck, who provide this data.
