矮人矿脉

Text:

（：加。）
除非你操控三个或更多其他山脉，否则矮人矿脉须横置进战场。
当矮人矿脉进战场且未横置时，派出一个1/1红色矮人衍生生物。

Rulings:

• 10/4/2019 An Island is a land with the subtype Island, not any land that could produce blue mana. For example, Mystic Sanctuary is an Island, but Castle Vantress isn’t.
• 10/4/2019 As these lands are entering the battlefield, they check for lands that are already on the battlefield. They won’t see lands that are entering the battlefield at the same time (due to Scapeshift, for example).
• 10/4/2019 If another effect puts these lands onto the battlefield tapped, they enter tapped, even if you control enough lands with the appropriate basic land type.
