Raging Ravine - Commander: Lorwyn Eclipsed (Rare) [ECC-160]

Raging Ravine is a land from the Lorwyn Eclipsed Commander set that taps for either red or green mana but enters the battlefield tapped. For a cost of two colourless mana and one red and one green, it can become a 3/3 Elemental creature until the end of turn, gaining a +1/+1 counter each time it attacks. This dual functionality makes it a solid choice for aggressive Gruul decks that benefit from both mana fixing and a beatable creature on the battlefield.
