I was playing it with my friend that came over on this, of course. He was introduced to it by an online friend, and he showed it to me.
It's hard to say this: I had fun playing yugioh. There's no longer that feeling that you can't duel at your fullest because you lack the cards, or the frustration of knowing that you don't have a lot of customization.
This place has every yugioh card made thus far (Except cards from the anime.). You can make whatever deck you want, However many you want (I went as far as 25 new decks and it still let me make more. xD). Plus, it supports both TRADITIONAL (No ban lists/restrictions!) and ADVANCED (For blokes like me that like a little limitation on how people murder me in a card game.) formats. There's also a ranking system, but you can choose not to participate in rankings (Like me! I do unrated all the time.)
Also, Exceed monsters (The new monster cards) are coming soon to it as well once some high quality scans from Japan get in and it gets translated.
Currently, I run the following decks:
Ritual (Mixed rituals.)
Gishki (Awesome ritual archtype that everyone says that it sucks for whatever reason. It's amazingly fun.)
Aliens (Really fun! You may have to keep track of tokens for me. I lose count a lot of times. D: )
Fusions+Rituals+Synchros, With a pinch of Red Eyes B. Dragon. (Exactly as it says)
Karakuri (Uh, Yay?)
(WIP) Dark magician deck
Minus the aliens, you can probably tell I <3 rituals.
The only complaints I have with this program is that you can't add/subtract counters onto cards and there's no tag dueling. Other than that, it's gorgeous.
* Fox McCloud awaits being called a n00b or a retard for still playing yugioh.
Yes, the post recordings are still on schedule. I'll be starting Hikaru's requested post tomorrow. I don't have an ETA on Lyoko's yet.
