Bounce Off

Unsummon has been the reference point for single-blue bounce since the earliest days of the game: one mana, instant speed, one creature back to hand. The wrinkle in this iteration is the target line, which reaches Vehicles alongside creatures. That widens the answer from "reset a blocker or save a threat" into a clean, permanent-free response to a crewed attacker, sending the Vehicle back to hand and wasting the tap that its pilots spent to power it. Bounce at one mana has always been a tempo tool rather than an answer: it does not deal with the permanent, only delays it, so its value scales with how expensive the thing you return was and how far behind on the board you are. The instant-speed window is what earns the slot, letting the caster hold up interaction through a turn cycle and untap into it, or return an about-to-die creature to save it from a removal spell (note that any aura attached to it falls off to the graveyard rather than following it home). Against a Vehicle deck the calculus tightens further: a bounced Vehicle costs its controller the recrew, which can be an entire attack step's worth of tempo. The card asks nothing beyond a single untapped Island, and it trades a card to buy a turn, a deal that only pays when the turn is worth more than the card.
