"Genex" (ジェネクス Jenekusu) is an archetype of mostly Machine monsters with various Attributes (primarily DARK) that exist in the TCG/OCG. Most of their effects involves adding monsters from the Deck to the hand and Special Summon them, as well as using "Genex Controller" with low-Level monsters of the four basic Attributes for Synchro Summon. The name of "Genex" Synchro Monsters takes after sources of energy such as hydroelectric, geothermal, solar, etc.

"Genex" monsters were introduced in "Duel Terminal - Invasion of Worms!!". Two more sub-archetypes were added in "Justice Strikes Back!!", "Champion of Chaos!!" and "Charge of the Genex!!": "R-Genex" and "Genex Ally", respectively.

Playing style

In terms of viability, the "Genex" archetype suffers from having purely monsters and no Spell/Trap support. While the main archetype mostly revolves around the use of "Genex Controller" to achieve various effects and perform Synchro Summons of the Extra Deck monsters, "R-Genex" focuses on assisting the Special Summon of Genex and "R-Genex" monsters for swarming, and "Genex Ally" focuses on manipulating the six attributes to achieve different effects.

It is nearly impossible to build a Deck centering around "Genex" monsters since their effects have little to no relation to each other. Instead, some useful "Genex" monsters are listed below:
