Obviously, this reprint will put a huge dent in the prices of the original Zendikar printings of these five lands. At the time of the announcement, Arid Mesa was $50, Marsh Flats was $35, Misty Rainforest was $45, Scalding Tarn about $75, and Verdant Catacombs around $60. The supply of these was getting low due to pretty much every Magic player wanting at least four copies of each. They’re playable, and very good, in every format outside of Standard. Fetch lands not only fix mana quickly at the cost of only a single point of life, but shorten the number of lands that you draw, as well.
These are some great lands to open not only for drafting and sealed deck purposes. These lands will be good to open for collection purposes and deck building, as well. The fetch lands themselves will likely sell the set.
