But the main reason that it has been such an interesting card financially is that it's played in several modern decks. the most popular of these two are Bant Eldrazi and Green & White Tron. Both of these decks require colorless Mana costs. This is especially true of Bant Eldrazi which requires colorless mana to cast Thought-Knot Seer and to activate the ability of Eldrazi Displacer.
With Modern season right around the corner this is a good time to pick up your copies of Brushland. Even with so many different printings available this card is so popular that it's sure to sell out as soon as people start building more of these particular decks. my favorite printing is the original Ice Age printing, although Brushland is also available from 5th Edition, 6th Edition, 7th Edition and 10th Edition.
