Ahhh MTG. I miss it, but can't afford to go back. I haven't played since I sold my collection about a year and a half ago to help pay for my wedding.
I loved Commander (used to be called EDH) multiplayer (more than 2, I found 5 was the best). One of my fondest memories was being a DCI judge for some of the tournaments back in the day when Wizards of the Coast had a physical store out in Santa Monica.
