Technology vs. Tyrannos! Take part in the ultimate battle between man-made monstrosities and the greatest predators nature has ever produced with the Machine Reactor Structure Deck and Dinosmasher's Fury Structure Deck.

The Machine Reactor Structure Deck uses the popular “Gadget” series of monsters, most recently seen in Movie Pack Gold Edition, to power up gargantuan “Ancient Gear” monsters. You can add your Gold Gadget and Silver Gadget from the Movie Pack to this Deck to help Summon the new Ancient Gear Gadget – a monster that belongs to both themes and turns this Deck's ace monster, Ancient Gear Reactor Dragon, into a 3000 ATK double-attacking, defense-piercing, card destroying behemoth!

For those of you who prefer natural history over mankind's machinations, the Dinosmasher's Fury Structure Deck provides the ultimate prehistoric Dueling experience! It's survival of the fittest, and only the strongest cards in your Deck will make it. The rest will be food for the apex predator, Ultimate Conductor Tyranno, a 3500 ATK monster that can send all enemy monsters cowering in fear before devouring them all in a single Battle Phase!

This Deck is adept at Summoning multiple Dinosaurs of the same Level at the same time, and most of those monsters are Level 4. That makes this Deck a perfect fit for Xyz Summoning! Duelist Saga and Maximum Crisis both have great Rank 4 Xyz Monsters that are perfect fits for this strategy.

• Each Structure Deck comes with a 41-card Main Deck and 1 Token Card for a total of 42 cards.

This Machine Reactor and Dinosmasher's Fury - Structure Deck Display (1st Edition) contains 08 Decks in Total!
