Wildwood Rebirth

The instant-speed clause is the entire reason this exists, and it is doing quiet work most green creature-recall does not. Green has always had cheap ways to buy a body back from the graveyard, but the bulk of it runs at sorcery speed: you spend your main phase rebuying a creature and hope it matters. Doing it at instant speed changes the math around combat and removal. A creature dies blocking, or eats a targeted kill spell, and once it hits the graveyard this returns it before your opponent has finished their turn, so a trade you just lost can be re-armed at their end step, or held up going into a future blocking step of your own. The creature does have to die first: this cannot save a body mid-resolution, since the card is not yet a legal target while it is still on the battlefield. Nor does it reanimate anything (the creature lands in your hand, not in play), which keeps the rate honest: you still have to recast whatever you got back, so this is a tempo-neutral rebuy, not a free loop. That same restriction makes it a clean fit for decks built on creatures with enter-the-battlefield triggers, where returning a body to hand and replaying it is the plan rather than a consolation prize. It sits below green's heavier reanimation, but the instant-speed window is a real distinction, not a cosmetic one.
