This deck needs to have Future Fusion, Five-Headed Dragon, and 3 Eclipse Wyvern. That's how this deck does its thing. 2 Gachi Gachi is absurd, 1 can go to make room for Five-Headed, and remove 1 Divine Dragon for a Wyvern, the other for Future Fusion. Reaper is a better side card for this type of deck, so it can go there. After that, You don't need 2 Red-Eyes Wyverns; they should become a DAD and a Lightpulsar. Personally, I think 3 Ryko is overkill; I'd side the third, and remove Jain, and bring the deck to 40 cards. Oh, and MST is far, far better than Night Shot.
