Does it trigger every upkeep you have?
{rebound}
It's an instant spell and will only change the target of one spell once?
This question isn't making any sense coming from you, unless I'm missing something.
702.87a (http://imtgapp.com/forum/index.php?action=imtg;area=rule;number=702.87a): Rebound appears on some instants and sorceries. It represents a static ability that functions while the spell is on the stack and may create a delayed triggered ability. "Rebound" means "If this spell was cast from your hand, instead of putting it into your graveyard as it resolves, exile it and, at the beginning of your next upkeep, you may cast this card from exile without paying its mana cost."

im asking about the mechanic in general
Yep
It's why I listed a card with the mechanic
The question makes a lot more sense now.
