Countersculpt

At three mana it trails Negate and Disdainful Stroke on tempo; a hard counter plus a one-loyalty Jace token is plausible in 4-Color Control.

Could be wrong if A dense pool of playable Jace or Empower cards could make the UU mode consistent and raise adoption.

Azorius Control can test it as a universal answer, but it is slower than Disdainful Stroke and its token has little value without repeat Empower.

Could be wrong if Playable Jace enablers could make its conditional UU hard-counter mode much more reliable than expected.

The normal 2U cost is slow for Modern; without reliable Jace setup, its small token payoff does not match efficient interaction like Mystical Dispute.

Could be wrong if A proven Jace-token shell that consistently enables the UU mode could give it a niche.

UWx Control could test it, but its first copy is usually 2U and the token is too minor against Legacy efficiency; Consign to Memory is stronger in its niches.

Could be wrong if Reliable Jace-token setup could make later copies efficient enough for a specialized blue control shell.

Jace decks can reveal a Jace for a two-mana hard counter and gain a token, but singleton makes repeated Empower and token growth unreliable.

Could be wrong if Additional Jace-token or Empower support could make the token a real engine rather than a one-shot surveil.

A 2U hard counter that leaves a one-loyalty surveil token is playable, but holding up mana and the UU cost constrain it; Jace setup is uncertain.

Could be wrong if Unknown Draft speed, bomb density, and Jace/Empower support could substantially alter how valuable the counterspell is.
