Of course, anyone that wants to duel me to see him is welcome to( he doesn't make an apearance in every duel) There are more ways to combo to bring him out than most people think( i know at least 5 now wher before i only knew 3) and there is no definite skeletal build for him, there are about 20 to 25 cards that every deck running him needs but after that it's all up to the individual. The great thing about him and his deck is that any deck built around him flows smoothly and works together. I run 2 decks with him and am trying to build more so that i can find every way to use him. The one drawback is that a deck with him is all dragons so if your opponent has cards that target dragons or are more effective aginst dragons your screwed. The most important thing is that you use monsters that have effects otherwise the deck is weakened greatly.
