Runaway Steam-Kin

A storage battery that charges off your own gameplan. The 1/1 body is irrelevant; the engine is the loop between casting red spells and the three counters those casts accumulate. Spend the counters for triple red, dump that mana into more red spells, and each of those refills the battery on the way back. The trigger caps at three counters, so you cannot stockpile beyond a single discharge, and the recharge speed is gated entirely by how dense your deck is with red cards. It rewards a specific kind of construction, low-curve and mono-red enough that nearly every spell is fuel, and it punishes the diluted manabase that would stall the wheel. The mana it produces is genuinely free: you are not paying life or cards for the burst, only the tempo of waiting three casts between discharges. That turns it into a payoff for going wide on cheap spells rather than a combo piece demanding a dedicated enabler. Its spiritual ancestors are the rituals that traded a card for a mana spike; this trades nothing but time, and it asks you to keep casting to keep the wheel turning.
