Gary, the Snail - Toxrill, the Corrosive (Rainbow Foil) Price

Updated 2026-10-01

Gary, the Snail in the Rainbow Foil treatment from the Secret Lair Drop Series is the SpongeBob SquarePants promotional version of Toxrill, the Corrosive, one of the most impactful Mythic threats in black Commander. Toxrill places slime counters on opposing creatures at end of turn and sacrifices those that accumulate enough counters, generating Slug tokens that tap for mana as each death accrues, making it an engine that grinds down opposing boards while building resources. The Rainbow Foil treatment is a visually distinctive finish that commands a collector premium over the standard foil, and the SpongeBob crossover adds IP-driven collector demand on top of Commander player demand. The three-month view shows a modest decline, but the past month has reversed course with a small uptick, suggesting the correction is stabilizing rather than continuing. The SpongeBob crossover has a dedicated collector community that sustains a floor independent of the Commander metagame. This is a recovery candidate at the current level.
