Aether Inspector

Some triggered abilities state that you "may pay" a certain amount of energy . You can't pay that amount multiple times to multiply the effect. You simply choose whether or not to pay that amount of energy as the ability resolves.

If an effect says you get one or more energy , you get that many energy counters. To pay one or more energy , you lose that many energy counters. You can't pay more energy counters than you have. Any effects that interact with counters a player gets, has, or loses can interact with energy counters.

Energy counters are a kind of counter that a player may have. They're not associated with any specific permanents.
