Harnessed Lightning

Burn that pays you for shooting big, with a catch worth reading carefully: the energy and the damage both live on resolution, not on the cast. Target a creature, gain three energy as the spell resolves, then decide how much of your stockpile to pour into damage. Because none of that happens until resolution, countering the spell or removing its target leaves you with nothing (no counters, no damage), which is a meaningfully different profile from a spell that banks its resource on announcement. Cast it bare and it is clean three-damage instant-speed removal that happens to leave nothing behind; cast it atop a reservoir built across earlier turns and it scales into an answer for almost anything on the board. That dual nature is the design wrinkle: the card is simultaneously a payoff and an enabler, refilling the resource it can also deplete, so a deck runs it as early interaction and late kill spell without ever swapping a card. The three energy is unconditional, so even a list with no other energy interactions gets the floor; the ceiling only matters if you build toward it. What balances the upside is arithmetic: every point past three spends a counter you had to manufacture somewhere, so the spell rewards a deck that treats energy as currency rather than flavor. It remains the cleanest argument for why energy worked at all: a resource you spend to make individual cards better, proven out on a removal spell.
