This resembles Pegasus' Deck used in Season 1.
I also used yugioh.wikia.com to make this deck as accurate as possible.
*Not all 40+ cards of his deck where known, so I added cards that fits his theme.
*I didn't use any Anime exclusive cards.
*I felt he should have a "Raigeki" as the creator of the game and main antagonist of season 1.
*"Killer Needle" was seen in his Deck in the japanese version of the anime, after he lost to Yugi, but is just to random for his Main Deck in my opinion.
*"Shine Palace" would be pretty dead in this Deck.
*"Bickuribox" was a Normal Monster in the anime.
