I used to be obsessed with the series. In fact, it went to the point where I wasted nearly 500$ trying to get an Ultra rare card.Of course, my friends played a part in it, and it was actually them that got me into it.Overtime, I lost interest and soon realized one of my friend's true intention, but that's a different story. My friends soon lost interest and I had no one to play with; I ended up selling all my cards. :(
Really, I do like the series, but I haven't had a chance to play it since.
