Official rulings
The 8 most recent official rulings for Electrosiphon, newest first.
If an effect says you get one or more {E}, you get that many energy counters. To pay one or more {E}, 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.
For spells with {X} in their mana costs, use the value chosen for X to determine the spell’s mana value.
Some spells and abilities that give you {E} 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 {E}.
{E} is the energy symbol. It represents one energy counter.
Some triggered abilities state that you “may pay” a certain amount of {E}. You can’t pay that amount multiple times to multiply the effect. You simply choose whether or not to pay that amount of {E} as the ability resolves.
Energy counters aren’t mana. They don’t go away as steps, phases, and turns end, and effects that add mana “of any type” can’t give you energy counters.
Some triggered abilities that state that you “may pay” a certain amount of {E} describe an effect that happens “If you do.” In that case, no player may take actions to try to stop the ability’s effect after you make your choice. If the payment is followed by the phrase “When you do,” then you’ll choose any targets for that reflexive triggered ability and put it on the stack before players can take actions.
