If Gemstone Caverns is in your opening hand and you're not playing first, you may begin the game with Gemstone Caverns on the battlefield with a luck counter on it. If you do, exile a card from your hand.
: Add Colorless to your mana pool. If Gemstone Caverns has a luck counter on it, instead add one mana of any color to your mana pool.
