The colossal Machina army is on a quest for revenge in the Yu-Gi-Oh! Structure Deck: Mechanized Madness. First appearing in the Machina Mayhem Structure Deck, the Machina monsters Antriebsrahmen and Maschinenwesen Festung have spread widely since their debut. Now, over a decade later, they are back with support from the Machina arsenal and stronger than ever. The Machina Citadel boasts an impressive 3000 ATK life points and a quick effect that can decimate your opponent's monsters by transforming one of your controlled machines into an explosion of shards. If your opponent manages to destroy your Machina Citadel, it can reassemble itself from the graveyard when an Earth Machine you control is destroyed. However, you can also let your own Machina trigger this effect after you send it to the graveyard.
