Quote from fnord »They're not going to mix old and new frame cards in these. That's the reason for the quantum reprints. So Swiftclaw and friends are in M15.
The sample decks have always had cards from other recent sets peppered in. It doesn't mean they're seeing reprint in M15. It seems to me the previewed cards are being reprinted so they can do their job of introducing basic concepts to new players without gumming up the booster packs of more experienced players. It doesn't have anything to do with the border. They could have just put M13/14 versions in, but they didn't because they want new players to be able to play with their cards, so they had to keep the contents standard-legal. Personally, I think it's genius. Every time I opened a Nightmare or Shivan Dragon out of M14 I got angry my rare slot was being taken up by a card with a thousand prior printings that would never be worth playing in standard, so why did they keep reprinting it? Now I realize they were including those cards just for brand new players. Thank god they found a better venue.
