So in Rage of the Abyss, Konami gave Bandit Keith and Joey Wheeler some legacy support, referencing their duel in "Yu-Gi-Oh! Duel Monsters." The two most important monsters in the Enhanced Metalmorph engine are Metalzoa X and what I'm using in this deck: Red-Eyes Black Fullmetal Dragon.
REBFD has three effects. You can reveal it in your hand to set a Metalmorph trap from your Deck, and shuffle this card into your deck. Also, if your opponent activates a card or effect, you can negate the activation and inflict damage to your opponent equal to the original ATK of one of their Attack Position monsters. REBFD must first be Special Summoned by "Enhanced Metalmorph" by Tributing a Level 5 or higher Dragon.
You know what has exactly that, and likes to go first? Dragonmaids. Many monsters in the archetype are high-Level Dragons, and Dragonmaid Sheou in particular is an omni-negate. Once you use Sheou's negation effect and tag out into House Dragonmaid, you can Tribute her with Enhanced Metalmorph to summon REBFD. Alternatively, you can revive a Level 5 or higher Dragon with Sheou's other effect, and then tribute it with Enhanced Metalmorph for two negates on board.
Finally, if you can end your turn with Hieratic Seal of the Heavenly Spheres and a set Enhanced Metalmorph, you can summon a high-Level Dragon with Heavenly Spheres's effect after tributing Spheres to bounce an opponent's card, and then activate Enhanced Metamorph to get a boss monster out.
As for this deck's name, it's called "J-Metalmorph" in reference to Japanese metal. I just started listening to Babymetal, among other bands and artists, and Babymetal is my favorite J-Metal band.
