This deck uses parts of the soon-to-be-released Zenet alongside LADR, blue-eyes, red-eyes, primite and angelechys to fill the extra deck. With a bit of Dark Magician thrown in as well.
Zenet can be used to get Dark Magician on the board, then go into Magician of Destruction to search Eye of Timaues for Dark Dragoon, likewise Lordly Lord can do the same thing
Black Metal Dragon goes into Spirit, which can then be used to get a board breaker with Burst Stream by sending Mausoleum to the grave. The Black Metal Dragon line will also grab max metalmorph and end with hevenly spheres, which will grab bystial which will not only let you summon full metal dragon but also let you grab ether during end phase for full primite combo, on the next turn with burst stream in your hand for board breaker as Lordly Lord will be able to summon Blue-Eyes.
LADR works pretty independently; it's mostly just for fun, but it can go into Dark Magician of Destruction if you sack Dark Chaos, but I think using the LADR rituals with Mind Shuffle is better or at least more fun, than just going into Dark Dragoon.
Opening to E4 is just a fun-as-hell hand trap that will give your opponent a floodgate and you three-target banishes on your first turn (turn two) before even touching a single card in your hand
