So I gave this a try. For starters, I forgot to add Closed Heaven, but as you can see, I ran out of space in the ED. I pulled out Zombie Vampire, but Zombie Vampire is good to have two materials to pivot into either Closed Moon or Knightmare Phoenix, and the lack of that extra material hurts in the long term. Second, it's just combo for the sake of being combo. Any path gets to Orcust, but I'm following so many steps that it doesn't even feel worth the trouble. Ideally, the best opener is Millennium, since the other three archetypes can't search Millennium monsters, but Millennium can pivot into either Fiendsmith or Orcust, and Orcust can later pivot into Mitsurugi.
tl;dr: Not worth it, stick to Millenium Fiendsmith Orcust or Mitsurugi Orcust and keep the deck at 40 cards. Maybe someone better than me can find success with it, but the fact that I actually don't have enough space in the ED is the real deal breaker.
