Card Trivia:Polymerization

Although "Alternate Art" versions of cards are common in Yu-Gi-Oh!, Polymerization is one of only two cards (the other is "Dark Magician"/"Dark Magician (Arkana)") in the Japanese OCG where an "Alternate Art" version has a different eight-digit passcode as well. The "Alternate Art" of Polymerization is called Polymerization (Fusion).
