  1. Earliest archived Rules release700.1Details
    Anything that happens in a game is an event. Multiple events may take place during the resolution of a spell or ability. The text of triggered abilities and replacement effects defines the event they're looking for. One "happening" may be treated as a single event by one ability and as multiple events by another. Example: If an attacking creature is blocked by two defending creatures, this is one event for a triggered ability that reads "Whenever [this creature] becomes blocked" but two events for a triggered ability that reads "Whenever [this creature] becomes blocked by a creature."
