Card Trivia:Morinphen
- This card's name is derived from a similarly named card from Magic: The Gathering.
- Among OCG players, this card is well known as a joke card card (much like "Shapesnatch" in the TCG) due to it being a Level 5 Normal Monster with poor stats, but with just enough attack that it can't be summoned by a recruiter. Because of this, it has ranked highly among various user polls in Japan, notably in sleeve votes for both the OCG and Yu-Gi-Oh! Master Duel as a potential troll vote.
- Despite typically not winning, it often receives some merchandise as a consolation prize.
