Regrowth has been the two-mana green baseline for recursion since Alpha: return one card, any card, from the graveyard to hand. This bolts a command-zone reward onto that skeleton and pays for it by narrowing the target. Where Regrowth reaches any card in the yard, this one is pinned to permanent cards, so the instants and sorceries you flung earlier stay dead. That restriction is the price; the copy clause is the payoff. While you control your commander at the moment of casting, the spell duplicates itself and lets you point the copy at a second card, converting a one-for-one into a two-for-one whenever the board cooperates. The value hangs on the check the format is built to satisfy: keep the commander in play and the bonus is close to free, the same exposure every commander-matters card negotiates. The retargeting is optional, which matters for how the stack resolves: the cast trigger puts the copy above the original, so if your graveyard holds a single permanent card and both instances point at it, the copy resolves first and returns the card, while the original fizzles for having no legal target. Nothing is wasted; you simply lose the second half of the value when there is no second body to find. It is Commander-native design in the cleanest sense, an old effect handed a new axis by a zone that did not exist when the original was printed, with the tighter target range keeping the two-for-one from ever being unconditional.
