With Legacy tournament support dying, it's interesting that Wizards decided to print Mystic now. The art is pretty nice, although I'm partial to the original Worldwake art. What this will do is provide Commander players a much cheaper foil printing to "pimp" out their decks and she is indeed a staple in any Equipment-heavy EDH deck. Non-foil Stoneforge Mystics are about $20-25 as of this writing, but foils are over $100. The promo should be much closer to the non-foil price since there will be plenty of copies of these handed out during next year's Grand Prix tournaments. It's good news for anyone who wants this card, but I think most demand will come from Commander players.
