Sisay's Ring

The four-mana version of the colorless mana rock, sitting one notch up the curve from the two-mana Mind Stone family and one notch down from the six-mana behemoths. Spend four now to produce two colorless per tap, and you do not break even until the second activation: this is a ramp piece that pays you back slowly rather than a fixing tool that smooths your turns. That is the design tension every fixed-output rock has navigated since: charge less for one mana, or more for a bigger burst? Sisay's Ring took the latter answer, presenting itself as a building block for colorless-acceleration decks that want to climb fast toward their high-end, not as a card that helps a three-color deck cast its spells on curve. The colorless output is the catch and the point at once: it does nothing to fix colors, so it only earns its slot in a shell that wants raw, color-agnostic mass: big artifacts, costly colorless payoffs, or a finisher that does not care what shade of mana feeds it. Worn Powerstone and Hedron Archive later carried the same two-colorless-burst idea forward at different rates, but the core proposition here is the oldest one in the family: spend four now to reach a bigger number a turn or two early.
