An inexpensive Dark Magician combo type deck can be built. Farm for more Dark Magician Girl and Sage Stone. Farm Kaiba or grind on PvP for 1-2 Champion's Vigilance and ECons (destroys Cyber Angels and Phoenix). Keep Magician's circle, go full on Neos and Maiden of the Macabre for easy activation of Circles. Deck is not tier 1 but is surprisingly strong and an economical option to begin on PvP.
