753. When making new choices in this way, a player must choose to remake all choices made for a chain item, even if they choose to make the same choice that was previously made.
753.1. A player may not make choices this way that would be illegal or that would lead to an illegal state, even if there are no other options.
753.2. A player may not choose to make new choices for a chain item if there aren't legal choices that they could make in this way. In such a case, the instruction to make new choices is negated.
753.3. Restrictions and requirements applied to a chain item will also apply to new choices made for that chain item in this way. Example: If a card is played from facedown, it gains the restriction that it can only target game objects at the battlefield it was played from unless its targeting is restricted in such a way that choosing a unit at that battlefield is impossible. If a player makes new choices for such a card, they must still choose from among objects at that battlefield.
