A-Galvanic Discharge

The energy-as-modularity idea, done to its logical end. Most burn spells fix their output at printing: two damage here, three there, priced against a target you can name in advance. This one hands you two energy on resolution and then lets you spend whatever you've banked, so the spell's ceiling is a function of your board's history rather than its mana value. That inverts the usual burn math. A one-mana spell that pings for exactly two is unremarkable; a one-mana spell that pings for two now and scales into lethal once an energy engine has been humming for a few turns is a different card entirely, and the same piece of cardboard is both. The design lives on the tension between floor and reservoir: it costs one red and always does something, but the reward for building around it is open-ended in a way that fixed damage numbers never are. Note the target line, too: creature or planeswalker only, never face. That restriction is what keeps the scaling honest, forcing the energy to be spent on removal and grind rather than converted straight into a clock. It is a removal spell that gets better the more you've already been paid, which is exactly the loop energy decks are trying to run in the first place.
