Ion Storm

The fuel source is the whole pitch: a repeatable two-damage shock that costs counters instead of cards. Charge counters were the era's currency, and this enchantment is the burn-them-for-value sink they were begging for. Feed it the counters off a Pentad Prism, a Coretapper-pumped artifact, a proliferating engine, and each one becomes two damage at instant speed, pointed wherever you like. The activation per shot prevents free machine-gunning, but the real ceiling is supply: you fire as many times as you can build counters to remove. That makes it a payoff rather than an engine, the back half of a counter-accumulation plan that needs a front half to matter. It reads charge counters and +1/+1 counters interchangeably, so it doubles as a removal valve for a creature you've overgrown or a Modular leftover sitting on a dying artifact. Most red removal of any era costs a card to cast; this one drains infrastructure you already deployed, so its value tracks the strength of the deck around it. Idle on its own, it just sits there. Built around, it converts a slow counter pile into reach you can aim at faces or threats without ever drawing another spell.
