2/9/2017 is the energy symbol. It represents one energy counter.
2/9/2017 Energy counters are a kind of counter that a player may have. They’re not associated with specific permanents. (Other kinds of counters that players may have include poison and experience.)
2/9/2017 Keep careful track of how many energy counters each player has. You may do so by keeping a running count on paper, by using a die, or by any other clear and mutually agreeable method.
2/9/2017 If an effect says you get one or more , you get that many energy counters. To pay one or more , you lose that many energy counters. Any effects that interact with counters a player gets, has, or loses can interact with energy counters.
2/9/2017 Energy counters aren’t mana. They don’t go away as steps, phases, and turns end, and effects that add mana “of any type” to your mana pool can’t give you energy counters.
2/9/2017 You can’t pay more energy counters than you have.
yes, this is better however crumbling vestige does have one very specific upside, you can use it to get the correct mana while contamination is up.
This situation is just so strange to me. Its not like this was a worthless rare. tendo ice bridge is $11 right now on tcg player mid.
Obviously aether hub has synergy with the new energy mechanic as well.
99% of decks could run either or and not notice any difference though.
