Gemstone Caverns

If this card is in your opening hand and
you’re not the starting player, 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.
{t}: Add {c}. If Gemstone Caverns has a luck
counter on it, instead add one mana of any
color. — "Fusion Gate"
