Bronze Cudgels

Most Equipment sells you a fixed bonus for a fixed price; this one sells you a variable, and the engine hides inside how the bonus accumulates. Each activation grants its own +X/+0 that lasts until end of turn, and X counts how many times the ability has already resolved: the first pump adds +1, the second adds +2 on top of it, the third adds +3, and because every one of those continuous effects sticks around simultaneously, the totals climb 1, 3, 6, 10. That is quadratic growth off a linear mana spend, and it is the whole reason the card exists. A flat mana sink gives you the same points per activation forever; this one pays you more for every mana you pour in past the first, so the gap between a modest investment and an all-in turn is enormous. The design problem it solves is the deck with a surplus of untapped lands and nowhere to spend them: instead of a static equip that hands over three points a turn regardless, this converts an open mana advantage into a curve that bends upward the longer you feed it. The cost of that ceiling is that nothing survives cleanup. The stacked effects all expire at end of turn, so each turn rebuilds from +1, and the card does exactly zero until you start committing mana. It is a payoff for going long that asks only for mana to burn when the board has stalled.
