Field of Ruin was printed in Ixalan to provide a check on the set's many utility lands, but it's starting to see some play in Modern, too. Most importantly, you won't have to worry about being down a land after sacrificing Field of Ruin, and you can even find the colored mana source you need to cast a crucial spell.
