A "Spell Card" is a game mechanic commonly found in trading card games, particularly in the Yu-Gi-Oh! series. These cards represent magical spells that players can use to gain advantages during gameplay. Each Spell Card has specific effects that can alter the state of the game, such as increasing a player's attack power or allowing them to draw additional cards. In addition to their strategic importance, Spell Cards come in various types, including Normal, Continuous, and Quick-Play. Each type has its own rules regarding when and how it can be played, adding layers of strategy to the game. Players must carefully choose and use Spell Cards to outmaneuver their opponents.
