"Gearspring", known as "Clockwork" (ネジマキ Nejimaki) in the Japanese version, is a series used by Bronk Stone in Yu-Gi-Oh! ZEXAL. It focuses on using the Gearspring Counters that each Continuous Spell Card spawns during your Standby Phase, which are used for ATK manipulation, to Special Summon monsters, and to inflict effect damage. In the anime, this series is meant to support Bronk's monsters, and it is worthy to be mentioned that fans sometimes refer to Bronk's monsters ("Tin Goldfish", "Tin Archduke", and "Aye-Iron") as "Wind-Up" knock-offs, and the OCG name for the "Wind-Up" archetype happens to be "Mainspring".
