I'm a big fan of Yu-Gi-Oh! for a long time, probably when the dub for the Duel Monsters of first series came out. Despite my interest in Yu-Gi-Oh!, I, myself, have never build a real-life deck, because I like the OCG better than TCG yet I cannot get hands on them, and several other reasons. Also, TCG sometimes mess up cards' texts.
My favourite archetypes that I would have to say are both Dragunity and Vylon, but i still like Vylon more than Dragunity. Not sure why, but I think because I like having to treat monsters as Equip Cards or treat others as Equip Cards.
