Psychic Corrosion (Rainbow Foil) Price

Updated 2026-09-15

Psychic Corrosion in Rainbow Foil is a mill-enabler that causes each opponent to mill two cards whenever you draw. In Commander, where the card advantage engine often runs at high velocity, the cumulative mill output of Psychic Corrosion can be substantial. The card anchors dedicated mill strategies in Commander and sees play as a value piece in draw-heavy blue decks. Rainbow Foil is the premium tier of Secret Lair production and is the scarcest version of this printing. The 7-day, 30-day, and 90-day windows are all positive, showing consistent appreciation. This is a card where Commander format demand aligns with collector scarcity in the Rainbow Foil treatment, producing a durable upward trend. Mill as an archetype remains popular among Commander players, and any new mill-enabling card printed brings players to the strategy who then look to complete the core package.
