Artful Maneuver

A pump spell that pays you back, but on the slowest possible schedule. Rebound turns +2/+2 into a two-for-one across two turns: cast it from hand at instant speed this turn, and instead of hitting the graveyard the spell is exiled as it resolves, waiting for you to recast it for free at the beginning of your next upkeep. That upkeep timing is the whole catch. The first cast is yours to fire reactively, saving a blocker or pushing damage through, but the rebound cast is bound to a fixed window you don't control: it comes up before you've drawn, before combat, at a moment when the board may have shifted entirely and the creature you meant to pump is dead or elsewhere. What you buy for is total mana value, the +2/+2 resolving twice off a single payment, which is the kind of card-advantage math white combat tricks almost never get. The lineage runs through every "buff that comes back" experiment rebound produced, and the tension is the same in all of them. A trick wants to be held until the perfect moment; rebound wants to be spent as early as possible so the free half arrives sooner and finds something to land on. Those impulses pull against each other, and deciding when to fire the first cast so the second isn't wasted is the only real decision the card asks of you.
