Hubris

The cruelty is in the small print: "and all Auras attached to it." A normal bounce spell sends a creature home and lets its enchantments fall off into the graveyard, ending those auras for good. This one scoops the whole package back to hand instead, and that one clause flips the value math. Against an opponent who has loaded a creature with bestow or pump auras, it functions less like tempo and more like a tax: two mana to send half a dozen mana of investment back to its owners' hands, at instant speed, so every aura has to be paid for and recast. Note the plural, "owners'": each aura returns to whoever owns it, not whoever cast it. Bouncing a creature wearing an opponent's control aura or curse hands that aura back to the opponent, which is why this is a clumsier rescue than it looks. Plain Unsummon and its many descendants treat auras as casualties; this one treats them as cargo, refusing to convert any of that mana into permanent attrition. Whether that helps you depends entirely on who paid for the auras and who gets them back. It is a narrow card, sharpest in eras when creatures wear their value on their backs, and a strictly worse bounce when they do not.
