Rampaging Monument

A colorless artifact that pays you for going gold. The body arrives as a 3/3 with trample, unremarkable on its own, but the cast trigger fires on any multicolored spell regardless of which colors it contains, making it the rare counter-accumulator that any two-or-more-color deck can run without warping its mana. That color-agnosticism is the whole pitch: a counters payoff usually demands a specific color pair or a specific keyword to feed it, while this asks only that your spells be gold, then rewards you on the stack rather than on resolution. Because the trigger keys off casting, not resolving, it grows even when the spell that triggered it gets countered, and a single turn that chains two or three multicolored plays can vault it from a modest blocker into a genuine threat. The trample is the deliberate finisher clause: a creature that scales past chump-block range needs a way to convert size into damage, and trample turns each accreted counter into reach that single-blocker defenses cannot absorb. What sets it apart from most counters payoffs is the absence of a deckbuilding tax: it costs no color, demands no synergy piece, and asks nothing beyond a manabase that already wanted to run gold cards. It is a colorless invitation to lean into a multicolor identity that would otherwise go unexpressed.
