one piece booster box op 03 Card Game officially produced by Bandai. One Piece Trading Card Game

Cards like Prismatic Secret Rare or Ultimate Rare often hold higher resale value, making them sought-after for both collectors and investors globally

While it allows you to be able to swing in at an opponent and give all your creatures pseudo vigilance, it also does the same for everyone else

Sure, the Thunderbolt attack is quite expensive at three Lightning Energy, but when there's a need for a surefire attack, it's the only real option

Such fillers are apparently sometimes used in other TCGs (see The Collation Project on the topic of Magic: The Gathering) and are discarded after cutting (though I wouldnt be surprised if there are Jungle packs accidentally containing a blank card out there somewhere)
