Assembly-Worker is a seldom used creature type used for artifact creatures. It was first featured in Antiquities.

The creature type is based on the original rules text of Mishra's Factory, which initially listed two subtypes: Assembly and Worker. In the Grand Creature Type Update, both subtypes were joined by a hyphen.

Time Spiral revived the type for Urza's Factory and the Assembly-Worker.[1] The latter was the only creature card naming the creature type in its type line until the Kaladesh block added Self-Assembler in Kaladesh[2] as well as Cogwork Assembler and Foundry Assembler in Aether Revolt. Modern Horizons 2 added Academy Manufactor and Arcbound Prototype.
