Even being such an old card, printed at common several times, Aqua Madoor even made an appearance in the Yu-Gi-Oh GX anime. The normal-type Spellcaster was even reprinted at Secret Rare in Legendary Collection 3: Yugi's World Mega Pack, the first ever foil printing of this card.
My first experience with Aqua Madoor was in the Starter Deck: Pegasus, my introduction to the Yu-Gi-Oh Trading Card Game. I really liked to play him in face-down defense position, since opponents would often attack him blindly and take battle damage. While he's pretty underwhelming by today's standards, Aqua Madoor was a very useful monster back in the day for many duelists.
