## Description

Released in 2021 as part of the Magic Online Promos series, Stinging Study (card number 90070) is a rare Instant card that has found a dedicated following within the Commander format. The card requires five mana to cast, including one black mana, and offers a powerful risk-reward mechanic: the player draws a number of cards equal to the mana value of a commander on the battlefield, but simultaneously loses that same amount of life. This dynamic interaction makes it a compelling addition for collectors who appreciate strategic depth and unique card designs. Artwork for this release was created by Kieran Yanner, whose distinctive style brings visual flair to the Magic: The Gathering universe. While originally distributed through digital channels, physical copies of this promo card have become sought after by hobbyists looking to expand their collections with unique, non-regular set pieces. The card’s identity as a rare promo item adds to its appeal for those who value the history of Magic Online exclusives. For investors and casual collectors alike, Stinging Study represents a tangible piece of the game's evolving lore and mechanical innovation. Its bold black border and high mana cost make it instantly recognizable to experienced players.
