Rebound (If you cast this spell from your hand, exile it as it resolves. At the beginning of your next upkeep, you may cast this card from exile without paying its mana cost.)

Rulings (9)
If a spell with rebound that you cast from your hand doesn’t resolve for any reason (either because another spell or ability counters it or because all its targets are illegal as it tries to resolve), none of its effects will happen, including rebound. The spell will be put into its owner’s graveyard and you won’t get to cast it again on your next turn.

If you cast a card from exile this way, it will go to its owner’s graveyard when it resolves, fails to resolve, or is countered. It won’t go back to exile.

If a replacement effect (such as the one created by Rest in Peace) would cause a spell with rebound that you cast from your hand to be put somewhere other than into your graveyard as it resolves, you can choose whether to apply the rebound effect or the other effect as the spell resolves.

Casting the card again due to the delayed triggered ability is optional. If you choose not to cast the card, or if you can’t (perhaps because there are no legal targets available), the card will stay exiled. You won’t get another chance to cast it on a future turn.
