Most Counter Trap Cards have activation condition that only allow them to be activated in response to the activations of other cards or effects (usually to negate those activations/effects), although there are others that can be activated as Chain Link 1 if their activation condition is met, such as "Black Horn of Heaven", "Negate Attack", or "Parthian Shot"
