Stroke of Genius Price

Updated 2026-08-23

Stroke of Genius in Judge Promo form is a premium version of the blue instant that draws X cards for X plus one mana, or routes the effect at an opponent as a mill win condition. Judge Promos are distributed only to certified DCI judges, creating a supply ceiling fixed by the credentialing window when this promo was issued. Stroke of Genius is on the Reserved List, permanently protecting the base card from tournament-legal reprint and providing a meaningful supply constraint on all printings. The Judge Promo frame commands an additional premium for Commander players and collectors who pursue the complete Judge Promo catalog. The 30-day and 90-day windows both show positive movement while the 7-day is flat: the card has been steadily appreciating over multiple months. Judge Promo versions of functional Commander staples with Reserved List backing have historically proven durable at premium price points, as neither the base card nor this treatment faces future supply competition.
