Electropotence

The repeatable cost is the whole architecture here. Most enter-the-battlefield payoffs are free triggers that snowball on their own; this one taxes you every time, demanding per creature to convert its power into a burst of damage. That turns an aggressive board into a slow but flexible burn engine: each creature you flicker, reanimate, or simply cast becomes a scaled Lightning Bolt aimed wherever you need it, with no cap beyond your mana. Set it beside a sacrifice payoff like Goblin Bombardment and the difference is the trigger, not the targets (both hit anything): the damage fires on the creature entering rather than dying, so it keeps the body on the battlefield and pays you again the next time something arrives. That makes it the rare red enchantment that monetizes creatures coming in rather than going out, and it rewards blink and token engines specifically because they restage the enter event over and over. The tension is mana, not setup: a wide board generates more triggers than you can pay for, so the card favors a deck that produces a small number of high-power bodies repeatedly rather than a flood of one-drops. The body it lacks is the price of admission; what you get for up front is a static threat that never needs to attack to close a game.
