Each card typically includes artwork, a name, and specific attributes or abilities that define how the monster can be used in gameplay. Players can build decks using these cards to compete against others. These cards are often part of a larger game system that includes rules for summoning, battling, and strategizing. Collectors also value Monster Cards for their rarity and artwork, making them sought after by fans of the genre.
