Card Trivia:Hidden Armory
- The armor on the right looks like a traditional knight's armor from the Middle Ages, while the one on the left looks like a traditional samurai armor.
- The swords and samurai armor in this card's artwork also appear in the artwork of "Armory Call".
- This card's OCG name (Arms Hole) is very similar to the OCG name of "Armory Call" (Arms Call).
- The artwork could be considered a general pun on the idea of "Hammer Space" or where anime and video game character's keep various over sized objects when not in use.
