deftranceThey're not worth picking up unless you're a collector of promo foils or 100% new to the game (and even then, free starter decks at your LGS are a better option). Personally, I find these decks good teaching tools for those not familiar with Magic and would like to get some variety into their learning games. I'd pick them up since it's the last time they'll be doing these Intro Decks and I collect promos. If you're looking customize or upgrade your deck, picking up singles from your LGS , Star City Games, or other retailer is the most cost and time effective way.
