You can replace Lord Gaia with Arisen Gaia (since it has a DARK attribute) and you can replace Hat Trick with Performage Trick Clown (since it has a LIGHT attribute). Pay attention to the pattern between Warrior/Spellcaster types. Deck is broken and you get a good hand every time. Honestly I have not lost to any duelist with this deck... yet, which my win ratio remains undefeated as of late. This deck can summon The Knights within 3 turns less/or more depending on what you draw or strategize. Thanks!
Edit: You can mill The Legendary Dragons to the GY with Magical Hats if you got a Legend Of Heart and Warrior type monster in your hand. You can also use Shadow Mist for Destruction Virus as well as to add Prisma to your hand. Then you can use Prisma for Timaeus or the summon of the Knights. YOU CAN ALSO USE LEVEL 4 MONSTERS TO GO INTO LEVEL 4 RANK XYZ MONSTERS TOO!
For Example: Summoner Monk can bring out Prisma, Shadow Mist or Trick Clown for a Rank Summon. (Trick Clown is your best option so you can Rank up with its broken effect) to bring out DRAGON/WARRIOR/SPELLCASTER XYZ RANK MONSTERS! I forgot to add in the XYZs I used for this deck but you need Daigusto, Castel, Rebellion Dragon, Gagaga Cowboy, and etc! Thanks!
