Narset Transcendent
Legendary Planeswalker — Narset
+1 : Look at the top card of your library. If it's a noncreature, nonland card, you may reveal it and put it into your hand.
-2 : When you next cast an instant or sorcery spell from your hand this turn, it gains rebound.
-9 : You get an emblem with "Your opponents can't cast noncreature spells."

When resolving Narset’s first ability, if the top card of your library is a creature or a land card, or if you don’t wish to put it into your hand, it isn’t revealed.

If a spell that exiles itself as part of its own resolution, such as Volcanic Vision, gains rebound, the ability that lets you cast the spell again won’t be created. The spell will simply be exiled.
