Every noncreature artifact you control gets a body at the start of combat: a 3/3 flier with haste and crew 1, so the Signets, the mana rocks, the equipment sitting inert on the table all become a temporary air force. The animation buries its own catch, though. These become Vehicles, not creatures, until someone crews them, and an uncrewed Vehicle can't crew another; converting ten artifacts at once does nothing to satisfy the crew requirement. You still need real creatures on the ground to pilot the fleet, and crew 1 is only cheap if you have that power to spare. So the payoff scales with your artifact count but caps out on your creature count: a board of pure metal and no bodies animates into a squadron of grounded 3/3s nobody can fly. The chaos trigger works as a hedge for that exact failure state, dropping a Treasure and a 2/2 Alien to keep the plane doing something when its main text has nothing to convert, and doubling as a slow supply of the very creatures the crew cost demands. What makes this a distinctive planar effect is the reframing: it takes a whole category of cards most tables treat as fixed infrastructure and, for one combat step, turns them into attackers, provided you brought a pilot.
