part2: Not to forgot lightpulsar has amazing field presence, u can send light and dark to grave making the wall live at any time those conditions are meet. Don't think it is luck just proper deck building. Though thats a factor. Only the the next ban list will determine future of chaos dragons.

think there consistent because every w exception of spells are useful in grave for overall purpose of deck. When u shuffle chances of gettting variety of cards in grave increase. Not to mention they run tour guide and sangan which is its own engine. The tour guide engine is 1/10 of the deck it self. So they have multiple engines lightsworn and tour propelling overall purpose of deck of putting light and dark in grave.

The cards you want to mill are incredibly low but it's still a good ass deck nonetheless considering once they get a red eyes and a lightpulsar out dark hole and torrential and mirror force don't do shit
