Flash is the load-bearing word here, and it points the card at a job most blink effects cannot do. A Cloudshift or a Restoration Angel wants to protect a creature or re-trigger an enters-the-battlefield ability on your own turn; this one casts at instant speed and then, optionally, bounces a creature you already control. The combination is defensive in a way the rate hides: hold up two mana, let an opponent commit a removal spell to a key creature, then flash this in and return that creature to your hand in response, saving it and leaving a 2/2 wizard behind. The bounce is targeted and optional ("you may return another target creature"), so there is no downside when you simply want a flash body, and the "another" clause keeps it from looping itself. It also re-arms your own enters-the-battlefield triggers at the worst possible moment for the opponent, since the window opens during their turn rather than yours. As a piece of UW tempo design, it belongs to the family of cheap evasive-protection tools that ask you to keep mana up and play reactively, trading the certainty of a sorcery-speed effect for the leverage of choosing exactly when the rescue happens.
