宝石洞穴

Text:

若你起手的手牌包含了宝石洞穴，且你并非先手，你可以让它在场来开始游戏，且上面有一个运气指示物。 若你如此作，将你手上一张牌移出对战。
：加到你的法术力池中。 如果宝石洞穴上面有运气指示物，则改为加一点任意颜色的法术力到你的法术力池中。

Rulings:

• 7/1/2013 If multiple Gemstone Caverns are put onto the battlefield under a single player’s control before the game begins, the “legend rule” won’t put the extras into that player’s graveyard until just before the first player gets priority during their first upkeep step. There’s no opportunity to tap the extras for mana.
• 6/8/2016 A player’s “opening hand” is the hand of cards the player has after all players have taken mulligans. If players have any cards in hand that allow actions to be taken with them from a player’s opening hand, the starting player takes all such actions first in any order, followed by each other player in turn order. Then the first turn begins.
