Theorist's Proxy

Flash 0/3 plus an immediate card is a low-risk control stabilizer; later copies can convert the Jace token into incremental value.

Could be wrong if Control lists may prefer cheaper interaction or stronger threats over a nonattacking two-drop.

A card-neutral flash blocker fits slower blue decks, while sacrificing it can force through a key spell in counter-heavy games.

Could be wrong if Pioneer's efficient removal and stronger two-drops may leave it as a narrow control option.

Esper Blink can repeatedly refill the Jace token, but a two-mana 0-power cantrip body is modest against Modern's baseline rate.

Could be wrong if Blink shells may not want a defensive body without an immediate disruptive or offensive effect.

The flash cantrip blocker and counterproof clause have utility in blue control, but two mana without disruption is a substantial Legacy cost.

Could be wrong if One-mana selection and more impactful creatures may make this utility package too slow.

Blink and planeswalker decks can exploit recurring loyalty refills; otherwise it is a useful cantripping blocker with situational spell protection.

Could be wrong if Without repeat ETB support or Jace synergy, the effect is replaceable blue card selection.

A two-mana flash 0/3 that can immediately draw a card is excellent tempo-neutral defense, with surveil or repeat-copy upside.

Could be wrong if Set speed, removal density, and archetype incentives are unknown; a very aggressive format could reduce its value.
