I'm so skeptical of the use of Electrodominance.Its text reads:"deals X damage to any target where X is the CMC of the next spell you cast."This is the one-off ability of Vial Smasher the Fierce,who doesn't see vintage play.
NOTE:you can play Electrodominance as Quicken or as a mana-filter.But these funcitons are not essential.
