As long as the two worlds don't mix, fine. I've never liked GX, and actually stopped playing when it's cards became popular. If they allow GX's cards into the classics duels, it will change the dinamics of dueling and deck building, and not everyone will think it will change them for the best.
I could do that, but then, eventually, the only players left would be people who failed to learn how to properly interact with human beings - and the gods know what would be of you if left to your own devices. So I guess I'll stay. But, hey! Thanks for the info. Maybe GX isn't as bad as I though it was when I watched.
