Quote from arrogantAxolotl »My reaction? Go for it, dude.
Commander is casual Magic. I'm not going to strip away your ability to enjoy the game the way you want to just because you haven't forked over for outrageously expensive cardboard. Collector's Edition? Proxies? I genuinely don't care. As long as your cards are easily identifiable, you can always sit down and enjoy a game together with me.
What a wise man.
