Marvel is a tournament deck archetype. Marvel decks were often blue-green-red. Their strategy relied on spells to create lots and lots of energy counters coupled with Aetherworks Marvel to free cast large creatures such as Ulamog, the Ceaseless Hunger or World Breaker that could win the game in a couple of turns. Thought to be the premiere combo deck in Pro Tour Kaladesh, the all-in version proved to be unreliable and easily disrupted. An aggro-hybrid version emerged in the later stages of the Kaladesh standard, but due to the bannings of Emrakul, the Promised End and the superior combo of Copy Cat, the Marvel strategy was suppressed until the banning of Felidar Guardian after the release of Amonkhet. While the deck was not overwhelming unlike Copy Cat, the experience of occasionally losing on the fourth turn through Ulamog proved to dominate Standard, leading to the ban of Marvel on June 14, 2017.
