Stone by Sunlight

A cheap instant answer to large creatures with occasional protection utility; likely a selective maindeck or sideboard removal spell rather than a universal answer.

Could be wrong if The post-release field may center on creatures below four power, leaving the removal mode too unreliable.

This is much narrower than Fatal Push and other established removal, but cleanly killing large creatures at instant speed can justify a metagame sideboard slot.

Could be wrong if Better unconditional removal may leave too few matchups where the power restriction is acceptable.

It can answer oversized creatures, but two mana and a power restriction compare poorly with Modern's efficient, broader interaction such as Solitude.

Could be wrong if A concentrated field of large, high-toughness creatures could make its hard-destruction clause more valuable than expected.

Swords to Plowshares is cheaper and unconditional, so this conditional destroy effect has little reason to displace established white removal.

Could be wrong if A narrow artifact-synergy or large-creature matchup could support an unusual sideboard role.

It efficiently answers many major creatures and can protect an important creature from destruction, but misses utility creatures and exile-based interaction.

Could be wrong if Artifact synergies or a high density of large commanders could make both modes more desirable.

Two-mana instant removal for most meaningful late-game creatures is strong, and the indestructible mode is a useful combat or removal counterplay fallback.

Could be wrong if Unknown creature sizing and format speed could make the four-power threshold either routinely live or too narrow.
