"Heavy Industry", known as "Heavy Machinery" (じゅう Jūki) in the Japanese version, is an archetype of cards used by Cody Callus in Yu-Gi-Oh! ZEXAL.

Heavy Industry Card Origin
Digvorzhak, King of Heavy Industry Bucket-wheel excavator
Jumbo Drill Drifter
Road Roller Road roller
Strong Shovel Excavator Power shovel

Playing style

The cards focus on getting three members of the archetype on the field, and using combinations of their support cards to have all three on the field with their Levels changed into 5, to Xyz Summon "Digvorzhak, King of Heavy Industry", destroy the opponent's monsters, and attack directly with "Digvorzhak".

"Jumbo Drill" takes advantage of the others being on the field, and "Strong Shovel Excavator" supports the Level-gaining to Summon "Digvorzhak."

The cards in this archetype are all EARTH-attribute Machine-Type monsters, so they take profit from support for both. Basic Machine support like "Limiter Removal" allows "Jumbo Drill" and "Strong Shovel Excavator" to launch an extra powerful attack (and if possible or needed, "Road Roller"), and then if possible already, overlay them before they are destroyed by "Limiter Removal" for "Digvorzhak" or another Xyz Monster.
