What Triggers Trap Cards?

▶

Trap cards are triggered by specific actions or events during a game, such as the activation of a spell or monster effect, and can be set on the field before being activated during either player’s turn. The activation of a trap card is dependent on the type of trap card, with normal trap cards having a Spell Speed 2 and Counter Trap Cards having a Spell Speed 3, allowing them to be activated during different phases of the game, including the Damage Step.

Trap Card Types and Interactions
