Mind Stone

Two-mana colorless ramp that later cycles is slow for Modern; it is at most a testable UrzaTron or colorless-ramp option.

Could be wrong if A newly viable artifact payoff or slower colorless shell could make its ramp-and-cash-in package more desirable.

Legacy's fast mana and cantrips outclass a fair two-mana rock; only a narrow prison shell would plausibly test it.

Could be wrong if A prison deck specifically valuing both colorless mana and a low-cost redraw could retain a small role.

Jund Wildfire may test an artifact that reaches three mana and cashes in, but Ichor Wellspring supplies much stronger artifact-card economy.

Could be wrong if Artifact-synergy density and whether three-mana acceleration matters in the post-release Pauper field are uncertain.

Cheaper than Commander's Sphere and easy to cash in, but colorless-only mana confines it mostly to artifact, colorless, and slower ramp decks.

Could be wrong if Optimized multicolor lists may prioritize colored rocks and faster mana enough to reduce its adoption.

Two-mana acceleration with late cycling is playable in slower decks, but it neither fixes mana nor affects the board; revealed synergies add modest value.

Could be wrong if Draft speed, fixing, and the density of expensive payoffs are unknown.
