My opinion, in order to maintain fairness, is that everyone have a set of the same card deck.For example... if I played with just the core set, the opponent would as well. If you used an expansion, the opponent would as well.
If you didn't, you'd just be falling into the 'Magic' trap again and buying additional cards like crazy to gain an edge (or use proxies)... which I feel is a bunch of BS.
I guess I just like to keep it simple and fair. It makes the game more interesting.
