I don't actually have the deck, so I don't know many of the distinct combos, but basically, you use cards like spiral Flame Strike or Herold of the Arc Light to get OEGD, then get Advanced Ritual Art or Impcantation Inception with Prep, Pre-Prep, or HAR, than Ritual summon, keep in mind that Double I only works With Impcantations and AAR only works with Odd-Eyes Arc.
