Crop Rotation is a common one mana green instant originally printed in the Urza's Legacy expansion for Magic: The Gathering with art by DiTerlizzi. It was reprinted in Duel Decks: Nissa vs. Ob Nixilis with new art by Daniel Ljunggren. Based upon the eponymous practice of cycling agricultural crops, Crop Rotation allows a player to sacrifice a land in play to tutor another land card from their library. It is considered to be an auto-include in any deck that contains Gaea's Cradle. (The reverse would be true except for the cost of acquiring a Gaea's Cradle in the secondary market.) Crop Rotation synergizes with a variety of cards of every type in addition to all utility lands. This provides additional targets based upon the player, additional colors of mana available to the deck, and the strategy involved to achieve the deck's win condition. (For example, when playing my Simic Commander deck, I greatly enjoy casting Crop Rotation on my next turn after transforming Growing Rites of Itlimoc so that I can put Nykthos, Shrine to Nyx into play. Then, casting Eternal Witness to put Crop Rotation back in my hand and recast to put Boseiju, Who Shelters All onto the battlefield and proceed to finish comboing out for the win! Good times, especially when I can pull it off on turn six or seven.) On resolution, at its most simplistic and basic, Crop Rotation is an example of ramp and is almost never a dead draw. There are, however, multiple ways to render it useless by an opponent or one's own game play.
