Qian Dei, Infinite Precept

Prowess, lifelink
Whenever you cast an instant or sorcery spell,
Qian Dei deals 1 damage to any target.
{w}{u}{r}: The next instant or sorcery spell you cast
this turn has rebound. (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.)
