↑ Section 614. Replacement Effects
614.13 An effect that modifies how a permanent enters the battlefield may cause other objects to change zones.
- 614.13a While applying an effect that modifies how a permanent enters the battlefield, you may have to choose a number of objects that will also change zones. You can’t choose the object that will become that permanent or any other object entering the battlefield at the same time as that object. Example: Sutured Ghoul says, in part, “As this creature enters, exile any number of creature cards from your graveyard.” If Sutured Ghoul and Runeclaw Bear enter the battlefield from your graveyard at the same time, you can’t choose to exile either of them when applying Sutured Ghoul’s replacement effect.
- 614.13b The same object can’t be chosen to change zones more than once when applying replacement effects that modify how one or more permanents enter the battlefield. Example: Jund (a plane card) says, “Whenever a player casts a black, red, or green creature spell, it gains devour 5.” A player controls Runeclaw Bear and casts Thunder-Thrash Elder, a red creature spell with devour 3. As Thunder-Thrash Elder enters the battlefield, its controller can choose to sacrifice Runeclaw Bear when applying the devour 3 effect or when applying the devour 5 effect, but not both. Thunder-Thrash Elder will enter the battlefield with zero, three, or five +1/+1 counters, depending on this choice.
- 614.13c While applying a replacement effect that modifies how a permanent enters the battlefield, another replacement effect may cause a player to mill cards or exile cards from the top of a library. In that case, any card that is entering the battlefield from that library won’t be included in that effect, even though those cards are in the library as the effect is applied. Example: Ashiok, Wicked Manipulator has an ability that reads “If you would pay life while your library has at least that many cards in it, exile that many cards from the top of your library instead.” Breeding Pool is a land that reads, in part, “As this land enters, you may pay 2 life.” If an effect allows a player to play Breeding Pool from the top of their library while they control Ashiok, and they choose to pay life as Breeding Pool enters, Ashiok’s replacement effect will ignore Breeding Pool, because it is entering the battlefield, and the next two cards will be exiled.
