（：あなたのマナ・プールにかを加える。）
蒸気孔が戦場に出るに際し、あなたはライフを２点支払ってもよい。そうしない場合、蒸気孔はタップ状態で戦場に出る。

Rulings:

• 10/5/2018 Unlike most dual lands, this land has two basic land types. It’s not basic, so cards such as District Guide can’t find it, but it does have the appropriate land types for effects such as that of Drowned Catacomb (from the Ixalan set).
• 10/5/2018 If an effect puts this land onto the battlefield tapped, you may pay 2 life, but it still enters tapped.
