Era of Innovation

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.

Some spells and abilities that give you energy may require targets. If each target chosen is an illegal target as that spell or ability tries to resolve, it won't resolve. You won't get any energy .

If a spell or ability with one or more targets states that you "may pay" some amount of energy , and each permanent that it targets has become an illegal target, the spell or ability won't resolve. You can't pay any energy even if you want to.
