Feather, Radiant Arbiter {R}{W}{W}

Notes and Rules Information for Feather, Radiant Arbiter:

• Feather, Radiant Arbiter’s ability triggers whenever you cast a noncreature spell that targets only Feather and no other object or player. (2024-02-02)
• If you cast a noncreature spell that has multiple targets, but it’s targeting Feather, Radiant Arbiter with all of them, Feather’s last ability will trigger. In that case, each of those copies will also only target one of the chosen creatures. (2024-02-02)
• You control all the copies, and you choose the order the copies are put on the stack. The original spell will be on the stack beneath those copies and will resolve last. (2024-02-02)
• The copies created by Feather, Radiant Arbiter’s last ability are created on the stack, so they’re not cast. Abilities that trigger when a player casts a spell (like Feather’s own ability) won’t trigger. (2024-02-02)
• If the spell that’s copied is modal (that is, it says “Choose one —” or the like), the copies will have the same mode. You can’t choose different modes. (2024-02-02)

• If the spell that’s copied has an X whose value was determined as it was cast, the copies have the same value of X. (2024-02-02)
• You can’t choose to pay any alternative or additional costs for the copies. However, effects based on any alternative or additional costs that were paid for the original spell are copied as though those same costs were paid for the copy. (2024-02-02)
• Any choices made when the spell resolves won’t have been made yet when it’s copied. Any such choices will be made separately when the copy resolves. (2024-02-02)
• If a permanent spell is copied, the copies are put onto the battlefield as a token as the spell resolves rather than putting the copy of the spell onto the battlefield. The rules that apply to a permanent spell becoming a permanent apply to a copy of a spell becoming a token. (2024-02-02)
• The token that a resolving copy of a permanent spell becomes isn’t “created” and won’t interact with abilities that care about tokens being created, such as that of Case of the Pilfered Proof. (2024-02-02)
