Please Rate or fix my Yugioh Zombie deck!?

Ive rated/fixed a lot of decks and I have to say this is one of the best ones that I have seen, definately the best zombie deck. Although the little bit of advice I would give is to add a marshmallon, remove the creature swaps and in there place add in a bottomless trap hole and sakuretsu armor. Also replace Enemy Controller with a 1:1 ratio monster destroying card such as Shield Crush or Hammer Shot. A card you may want to side deck is Chiron the Mage, I think he is often underestimated but in a deck so spell heavy knocking out opponents magic and trap cards with his effect could prove really useful. Lastly I might remove 1 Ill bud for Vampire Lord. I would rate this deck 9/10 seriously tournament competitive.
