This is one of very few Equip Spell cards that does not give any battle-related effect (i.e. ATK/DEF gain or protection from battle.)
Ironically, its only effect after the equip resolves involves the tributing of the equipped monster, when Equips generally meant to help a monster stay on the field or giving them a new ability on the field.
This is also one of very few Equip Spell cards that can be equipped to only 1 specific monster in the game.
Presumably, this is due to the card being themed around labyrinth - which is the "Labyrinth Wall" that appears in this card's artwork.
The spiral in the background of this card's artwork may be an homage to Fusion Summoning.
