Man oh man did I play a lot of this back in the day. Every Friday night a local bookstore had a gaming night and a group of us played. Had boxes upon boxes of the cards, a binder of printed out strategies and card information. Yeah, junior high and high school saw a lot of my cash going into those little packs, back when you could get them at Barnes and Noble, or any local card shop. I actually really miss it, even though I fell out of the game long before they stopped making them.
I too found the packs at the Dollar Tree recently and although the sight of them there made me a little sad and wistful, I certainly picked up a pack and grinned like an idiot opening them even though they were just first edition white borders.
