Trigon of Rage

Firebreathing rendered as a battery, with one wrinkle the colored-mana version never had: the activation targets any creature, not just one you control. Each +3/+0 spends a charge counter and a tap of the artifact, while refilling those counters costs and another tap apiece, so the engine drains faster than it refills. That gap is the point. The three counters loaded on arrival are a finite reserve you spend one tap at a time, and because every pump also taps the Trigon, you cannot dump them all in a single combat unless something untaps the artifact for you. With an untapper online, multiple activations can stack onto one attacker in a single combat to assemble one absurdly large body; without it, the +3/+0 trickles out a turn at a time. The recharge rate is deliberately punishing: two red and a full turn's tap buys back one counter you then fire for and yet another tap, so the arithmetic only favors the controller deep in a grind. Spreading the buff to any creature is the underrated angle, a surprise blocker boost or a way to shove someone else's attacker (or your own) into lethal. As a colorless source of repeatable reach, it gives red-leaning artifact decks a damage outlet that survives board wipes the way a creature never could, turning any evasive body into a clock the board state alone cannot answer.
