For Singularity, can you rechoose targets after your opponent responds (e.g., if they Gust one of the targeted units back to hand)?

Ruling: No, you cannot rechoose targets after your opponent responds. Singularity follows normal targeting rules where you declare targets first, then your opponent can react, but targets cannot be rechosen after that.

Sequence:

• Declare targets for Singularity
• Opponent has opportunity to respond
• Targets cannot be rechosen regardless of opponent's response

Nuances:

• Singularity is different from Falling Star in this regard (Falling Star does not follow these normal targeting rules)
