Rule 616.2 · Interaction of Replacement and/or Prevention Effects

A replacement or prevention effect can become applicable to an event as the result of another replacement or prevention effect that modifies the event.

Example: One effect reads “If you would gain life, draw that many cards instead,” and another reads “If you would draw a card, return a card from your graveyard to your hand instead.” Both effects combine (regardless of the order they came into existence): Instead of gaining 1 life, the player puts a card from their graveyard into their hand.
