Most lands that produce tokens stop at producing them; this one welds the token to a closed three-step loop, and the loop is the whole reason to run a colorless source that asks for no color of its own. Tap for one colorless to keep the lights on, spend four mana to grow a 0/1 Goat, then cash any number of those Goats in for an equal pile of one chosen color plus a point of life apiece. The conversion ratio is deliberately patient: each Goat costs four mana up front and returns exactly one mana of a single color, so the land never shows a profit in raw mana. What it banks instead is flexibility, saved over a quiet stretch of turns and redeemed in a single burst, which is the price that stops a colorless utility land from quietly fixing every color for free. The third ability also collapses the flock into one color rather than a rainbow, so the Goats are stored fixing and a lifegain cushion, not a Chromatic engine fired each turn. Tribal payoff, mana sink, and fixer in one slot, all riding on a land that enters untapped: that combination is why it has lingered in toolboxes with nothing better to do with a land slot.
