Cosmic Cube, Artifact, designed by Johan Grenier first released in Jun, 2026 in the set Marvel Super Heroes and was printed exactly in 3 different ways.
Cosmic Cube would fit best in an aggressive or midrange creature deck that reliably attacks with high-power creatures—such as Gruul Stompy, mono-green beatdown, or even certain Commander builds focused on large threats—because it rewards going wide or tall by turning combat into explosive card advantage and free spells; decks that can consistently attack with 5+ power creatures the turn after casting it (or immediately, via haste) benefit most. In Commander, especially in green-based stompy or Xenagos-style builds, it could be strong due to high power scaling and multiplayer value, but in faster constructed formats it likely competes unfavorably with more immediate-impact cards like The Great Henge (which provides card draw, ramp, and counters immediately and is often cheaper in creature-heavy decks) or even Sunbird’s Invocation for top-end spell cheating in slower builds. Because it costs five mana and does nothing until you successfully attack, it’s somewhat “win-more” and vulnerable
