Your standard Yu-Gi-Oh player. However, it's kinda boring when you can't find any challenging new opponents...
I live somewhere in Singapore, and hence play using English, Japanese, and Asian-English cards. A fair amount are Japanese due to the fact that their boosters are loads cheaper, and are also available earlier. Heh.
I have a little hobby of designing Decks for relatively interesting Deck Types, as my relative lack of capital restricts my deck designing to just the drawing boards. Some decks I have thought of involve Reverse Burn, Venom and Junk Warrior decks. And yes, I do take the trouble to thinking of names for them. If you find someone on YGOpro going by the name of Gadjiltron, it's probably me.
Other than Yu-Gi-Oh, I also play Touhou (6~14), Stepmania, Maple Story (retired), Duel Masters (retired), MtG and the Trauma Center series.
These are all the Decks I have planned out, but don't have the money to construct fully. You are free to use these decklists in constructing and testing certain ideas. Bear in mind that some are outdated due to the changing banlists.
Judai Yuki, but only from halfway in the third season onwards. That's where his character really becomes interesting as he is faced with trauma of putting his friends in danger, and it's also when his (somewhat annoying) duel-enthusiastic mood starts fading off.
