I have a deck of Yugioh cards that I'm pretty sure are mostly banned now. They weren't when I made it, though. It also is demolished pretty quickly with a well made deck of current cards. My friend who is still obsessed with the game looked at my cards and pretty much told me what I had was crap, but I remember losing very few games with it as a kid when I played in a Yugioh league they had in a Toys-R-us every Saturday. I don't remember what my strategy was though.

My favorite TCG is probably Redemption. The quick description is that it's like a Christian Magic the Gathering game, but that doesn't really do it justice. Aside from Magic, I believe it's the longest running TCG. While the cards are all based on biblical characters and things, the creator wasn't wanting to make a "Christian alternative" to Magic. He had no issue with Magic; he just wanted to create his own card game. In the end, I think it has the better gameplay. Another cool thing is that the cards all go through very extensive play testing, and its very rare for a broken card to come out. If one does, they weaken the card's effect, they don't ban it. There are no banned Redemption cards.
