cr:1.9.2a

If a triggered effect triggers from a multi-event, it does not trigger again for any of the individual events of that multi-event.

Example: Valda Brightaxe, has the text “Whenever an opponent draws 1 or more cards,” which is a triggered effect that would trigger once on a multi-event of drawing one or more cards, but would not then trigger on each individual event of drawing a single card from that multi-event.
