Rule 370.1.b.1

In the case of Replacement Effects that describe a game action to occur “as” an event occurs, the described event is replaced by that same event plus the game action being performed. Example: Undertitan is a unit that reads in part “As I’m revealed from your deck, [Add] [2].” The event of Undertitan being revealed from your deck is replaced by Undertitan being revealed from your deck and adding [2] Energy to your Rune Pool.
