Troll-Horn Cameo

A multicolor-heavy era needed mana sources that could feed gold spells, and this cycle of artifacts answered the call: five rocks, each tapping for one of the allied color pairs, with this one covering the red-green span. The price is the giveaway. Paying three to add a single mana of one of two colors was a rate the game had largely moved past with cheaper fixers, and the Cameos exist not because the rate is good but because the set's gold cards demanded the colors and the design team wanted artifact-based fixing that survived a color-screwed draw. The tap-for-one-of-two structure is the real design idea, and it sits early in the lineage of dual-producing rocks: where a basic land commits to a color, an artifact that offers a choice between two lets a deck splash without warping its land base. That flexibility came at a steep premium back when fixing was scarce enough to justify the cost, and it explains why these are footnotes today: the structure outlived the rate, and later rocks kept the choice while shaving the cost.
