Let's say you have a Pyromancer's Goggles and a Narset Transcendent out. If you -2 Narset to give Rebound to your next spell, if you copy that spell using Pyromancer's Goggles, does the copy also gain rebound? If so, how does that work?
Also, if I have a Jace, Telepath Unbound flipped and flashback a spell, could I give THAT spell rebound with Narset?
Narset specifies the next instant or sorcery you cast from your hand. Copies of spells aren't cast, so they don't gain rebound (Edit: Copying spells won't copy any abilities it's gained either). Jace allows you to cast the card from your graveyard, so it won't gain rebound either.
Also, if I have a Jace, Telepath Unbound flipped and flashback a spell, could I give THAT spell rebound with Narset?
