明炉戒

Text:

每当你起动异能时，若它不是法术力异能，则你可以支付。若你如此作，则复制该异能。你可以为该复制品选择新的目标。

Rulings:

• 11/10/2020 An activated mana ability is one that produces mana as it resolves, not one that costs mana to activate.
• 11/10/2020 You can’t pay <img src="/Handlers/Image.ashx?size=small&amp;name=2&amp;type=symbol" alt="2" align="absbottom" /> more than once for each time the triggered ability of Rings of Brighthearth resolves.
• 11/10/2020 If the ability has <img src="/Handlers/Image.ashx?size=small&amp;name=X&amp;type=symbol" alt="Variable Colorless" align="absbottom" /> in its cost, the copy uses the same value of X.
• 11/10/2020 The triggered ability of Rings of Brighthearth and the copy it creates both resolve before the ability that caused it to trigger. They resolve even if that ability is countered.
• 11/10/2020 The copy will have the same targets as the ability it’s copying unless you choose new ones. You may change any number of the targets, including all of them or none of them. If, for one of the targets, you can’t choose a new legal target, then it remains unchanged (even if the current target is illegal).
• 11/10/2020 If paying the activation cost of the ability includes sacrificing Rings of Brighthearth, the ability won’t be copied. At the time the ability is considered activated (after all costs are paid), Rings of Brighthearth is no longer on the battlefield.
