Magic: The Gathering TCG: Secret Lair Drop Series - A Box of Rocks - Foil EditionMagic: The Gathering TCG Secret Lair Drop Series A Box of Rocks is a collection of 5 Foil Alt Art cards: Arcane Signet, Chromatic Lantern, Commanders Sphere, Darksteel Ingot and Gilded Lotus! Mana rocks are the foundation (see what we did there?) of many games of Magic, but we never really see them get used in world. This drop explores strange and uncanny wizards from across the Multiverse using rocks we all know and love in an atypical pop art style.
