Is Vehicle

Artifacts with the Vehicle subtype, which are noncreature permanents until crewed (tapping creatures with enough total power) and then become artifact creatures that can attack and block. Covers aggressive staples like Smuggler's Copter, low-crew threats like Heart of Kiran, and bombs like Skysovereign, Consul Flagship and Parhelion II. Distinct from artifacts.is_equipment, which attaches to a creature via equip rather than crewing, and from the has_crew keyword tag, which marks the crew ability rather than the Vehicle type itself. A separate crew payoff ("whenever a Vehicle attacks") is a thin optional follow-on, not this detection tag.
