So you used to be okay with OTK's in Yu-Gi-Oh!? I couldn't stand them, I got out of Yu-Gi-Oh! back in 2004 when Ancient Sanctuary was the latest expansion and it was shortly around the time when Konami/UDE introduced the Forbidden/Limited List that CED and Yata Lock created so to speak. From Legend of Blue-Eyes White Dragon up until Invasion of Chaos or Dark Crisis was the best time to play Yu-Gi-Oh! in North America. Back then you had no Forbidden/Limited List and it seemed like everyone was on equal terms.
By now Yu-Gi-Oh! is too expensive for me to invest in even If I were to build a Casual deck for the game itself for fun with too many rulings and erratas, the power creep has gotten worse over the years, and alot of the decks being played in Advanced these days don't really interest me all that much. That and the Yu-Gi-Oh! Anime series is pretty much dead already, Zexal? The Yu-Gi-Oh! Anime hasn't been great since the very 1st series which is the best the franchise had to offer although 5D's deserves an honorable mention though.
