敲诈（每当你施放一个咒语时，你可以支付。若你如此作，则每位对手各失去1点生命，且你获得等量的生命。）
每当你横置一个沼泽以产生法术力时，加到你的法术力池中（会得到原本该有的法术力，并加上此份法术力）。

Rulings:

• 4/15/2013 You may pay <img src="/Handlers/Image.ashx?size=small&amp;name=WB&amp;type=symbol" alt="White or Black" align="absbottom" /> a maximum of one time for each extort triggered ability. You decide whether to pay when the ability resolves.
• 4/15/2013 The amount of life you gain from extort is based on the total amount of life lost, not necessarily the number of opponents you have. For example, if your opponent’s life total can’t change (perhaps because that player controls Platinum Emperion), you won’t gain any life.
• 4/15/2013 The extort ability doesn’t target any player.
