Avengers Quinjet

Most Vehicles pay off once, on the swing; the double trigger here turns a five-mana artifact into an engine. The choice fires on entry as well as on attack, so the recruitment or recursion happens the moment it hits the battlefield, before an opponent gets a combat step to react. Each mode is a resource conversion: cheat a Hero body straight out of hand onto the field for free, or buy one back from the graveyard to your hand. Because the enters clause rewards flicker, bouncing and replaying the Vehicle resets the trigger, so a deck stuffed with expensive Hero creatures can grind out mana-cheating advantage on repeat. Crew 3 is the tax that stops it from being pure gravy: attacking demands enough board presence to tap down three power, so the attack half asks you to already be ahead on creatures rather than rewarding you for falling behind. Flying gives the whole package an evasive delivery system instead of a wall. The design leans hard on a narrow creature-type constraint to justify the rate. Outside a dedicated Hero shell it is a 4/4 flier whose ability has nothing to grab: no Heroes in hand to cheat out, none in the yard to buy back. Inside one, it becomes a closed loop that treats your best bodies as a renewable resource, converting the same expensive creatures into value turn after turn.
