Mysterious Limousine
Blink effects usually settle a matter cleanly: exile a creature, it comes back reset, everyone moves on. This one refuses to settle. The exile lasts only until the Vehicle leaves the battlefield, so the removed creature is not gone but parked, a hostage whose release is tied to whether the 4/4 stays in play. Answer the Limousine (destroy it, bounce it, exile it in turn) and you are not just removing an artifact, you are springing whatever was locked inside. That conditional return is the whole tension of the design. The second clause sharpens it into a punishment for greed: trigger the exile again on a new target and every previously banished creature returns, but under its owner's control, not yours. A removal engine that hands your victims back the moment you reload is a strange knob to build a card around, and it forces the pilot to hold rather than spend: each attack or blink becomes a decision about which prisoner to keep and which to release. The trigger fires on both entering and attacking, so the card doubles as flicker fodder and an aggressor that clears its own path, temporarily jailing a blocker before combat damage. The machinery underneath elevates it past a simple value beater. It is a jail with a revolving door, and the door swings the moment you get too eager.
