A Box of Rocks was a five-card Secret Lair drop centered around some of Magic's most recognizable mana rocks, reimagined through a colorful and unconventional pop-art style. Artwork by Caramelaw, Mab Graves, Dani Pendergast, Theodoru, and Yosuke Ueno depicted unusual wizards interacting with the artifacts in ways that emphasized the playful concept behind the drop. The selection also gave the release strong Commander relevance, as mana rocks are a fundamental part of many Commander decks.
