Class Breakdown Cards

 are holographic cards that depict all of the game's pre-Season 1 Fighters, alongside three of their abilities and their respective Universe. They were first teased on the official social media accounts on March 15th, 2022 via gifs, with the first card revealed being of Shaggy.

This cards were eventually given out as exclusive collector items at the EVO 2022 MultiVersus booth. On August 23rd, 2022, Morty got a preview of his Class Breakdown card, confirming that the cards will eventually be given out again at future events, and future Fighters would be getting cards as well.

Trivia

 * The gifs also showcased the Fighters' archetypes via a moving bracelet, but this detail was not carried over to the real life designs, likely because they were impossible to recreate.
 * Garnet and Steven Universe are the only pre-Season 1 Fighters to have received promotional gifs of their Class Breakdown cards after the EVO 2022 tournament.
 * Coincidentally, they're both from Steven Universe.
