Black's most stripped-down piece of graveyard recursion: one mana, one creature card, back to hand, and nothing else attached. The card exists to be the floor of an effect, the version printed when a set needs the reanimation-adjacent option but wants it bounded and cheap. The restriction that prices it is the return-to-hand clause; you pay a full second cast to get the creature onto the battlefield, which keeps it honest against the splashier reanimator spells that cheat the mana cost entirely. That makes it a value spell rather than a combo enabler: it rebuys a creature you already played, it does not break the rules about how creatures arrive. Black has carried this exact effect across the game's whole history under a parade of names (Raise Dead being the original template), each printing a near-identical reprint at common, because the effect is too modest to warrant power-creep and too useful to retire. The line between these and the dangerous recursion is precisely the word "hand": once a card returns a creature directly to play, the rate changes entirely and the design moves into reanimator territory. This is the safe side of that line, and it has stayed there by design.
