Forests and Plains... white and green and artifacts mostly... Serra Angels, Regrowth... I still keep a crappy deck someone gifted me in order to play many years after, but as I worked in a collectible and geeky store, if I had kept them hahaha XD as I say, rather not to think much about it.
I also collected all lotr cards (including dragons expansion) , Legend of the Five Rings... those were the years I used to play and role game when I was in University.
