cr:1.9.1a

If an event comprises an instruction that involves elements outside the game, that event cannot be modified by replacement effects or trigger triggered effects within the game, unless the event directly interacts with the game.

Example: Go Bananas has the text “Open and reveal a booster pack of Flesh and Blood and put all cards with the chosen name into your hand,” which creates a ’reveal’ event and a ’put’ event as part of its resolution. The ’reveal’ event only operates outside of the game, so any replacement effects and triggered effects within the game do not interact with it. The ’put’ event directly interacts with the game by putting an object into a game zone, so replacement effects and triggered effects within the game may interact with it.
