5 facts about this card
This card represents Ogerpon’s Cornerstone Mask form, the mask that changes Ogerpon into a Grass/Rock Pokémon in The Teal Mask DLC and gives it a uniquely defensive identity among its forms.
Cornerstone Mask Ogerpon ex was part of Ogerpon’s first wave of Pokémon TCG cards, debuting when The Pokémon Company introduced all four Ogerpon ex forms in Scarlet & Violet—Twilight Masquerade.
Its attack, Demolish, is especially flavorful for collectors because it punches through effects on the opponent’s Active Pokémon, matching the card’s stubborn, fortress-like Cornerstone theme.
As card 160/131, this Special Illustration Rare sits in Prismatic Evolutions’ secret rare range, giving the pull that extra chase-card aura collectors love.
Pulling this in Prismatic Evolutions is a neat callback to Ogerpon’s rise in the TCG, because Prismatic Evolutions launched on January 17, 2025 after Ogerpon had already become one of the Scarlet & Violet era’s standout new Legendary Pokémon.
