Trigon of Thought

The whole point of this artifact is that it stores its own fuel and then makes you choose between spending it and refilling it. It enters with three counters, draws by spending them at two generic and a tap, and lets you bank more at the steep price of two blue and a tap. That asymmetry is the design: the draw is cheap and colorless, but the recharge is expensive and color-locked, so the device tends to deplete faster than it refills unless the deck has the mana and the turns to spare. This is a slow, repeatable card-advantage engine for the patient end of a game, not a tempo play. Five mana up front buys you no immediate payoff, and each card costs a full activation plus a counter, so it grinds rather than gushes. It belongs to a family of artifacts built on the same charge-counter chassis, each tuned to a different color's identity, and this is the blue node: card draw as the resource the counters meter out. Where most card-advantage rocks lean cheaper and faster, this one is deliberately throttled, a value sink that rewards a grindy, mana-rich game and gives nothing to a deck hoping to turn it on the moment it resolves.
