Static Discharge
Intensity is a digital-only mechanic built for a world where a card can carry state between castings, and this is the clearest demonstration of what that permits: a burn spell whose damage climbs every time you resolve one. The first cast deals three and goes to the graveyard like any sorcery, but the mechanic buffs every copy you own, wherever they sit, so the next one you cast deals four, then five, and upward across a game. That persistence is the whole trick. Paper burn is priced against a fixed rate because you know exactly what Lightning Bolt does every time you draw it; here the rate is a variable the client tracks per named card, a bookkeeping problem no cardboard set could shoulder. The floor is deliberately modest (two mana for three damage does nothing you couldn't get from a dozen older spells) because the design is renting power from the future, betting on repeat access rather than one big hit. It rewards drawing multiples and living long enough to fire them in sequence, which reframes a burn spell from a one-shot answer into an escalating threat, each copy a slightly bigger version of the last. As a proof of concept for what mechanics become possible once the client, not the player, is the referee, it matters more for the door it opens than for the damage it deals.
