What are white yu gi oh cards?

In the Yu-Gi-Oh! trading card game, white cards generally refer to Spell Cards. Spell Cards are one of the three main types of cards in the game, alongside Monster Cards and Trap Cards. Spell Cards have a variety of effects, such as summoning monsters, destroying cards, or manipulating the game state. They can be activated during either the player's turn or the opponent's turn, depending on the card's effect. Spell Cards are typically identified by their white color and the spellcaster icon (a wand and hat) in their top-right corner.
