Marvel Snap
Given the presence of Captain America et al, you might reasonably expect the character cards to be, well, the heroes of Marvel Snap. They’re certainly treated well enough. The card art plunders decades of Marvel comics, including the typographic logos that would traditionally announce these heroes and villains in speech balloons, all decorated with upgradeable visual flourishes that allow upgraded characters to break free of their card’s borders. These are paired with characterful special abilities: Doctor Strange uses portals to summon his most powerful allies to his current location, while serial killer Carnage destroys any placed next to him, powering up in the process.
