Trigger

A Trigger is the part of a Rule that describes when to run that rule. All rules have exactly one trigger.

Typically, triggers describe events that might happen while a Card is playing. For example, to destroy a block when the player taps the block, use the When this is tapped trigger, followed by the Destroy this actor Response.

List of triggers
