Changes

'''Structure Deck: Machina Mayhem''' is the sixteenth [[Structure Deck]] to be released into the [[TCG]]. It is the [[OCGTCG]] version of [[Structure Deck 18: Machiners Command]]. It introduces the [[Machina]] [[Archetype]] for the first time to the [[TCG]]. It focuses partially on [[Union Monsters]]. The differences from Machiners Command are the removal of [[Formation Union]], [[Combination Attack]] and [[Wave-Motion Cannon]], which were replaced by a second [[Armored Cybern]], [[Solidarity]] and [[The Big Saturn]].
