Reach
Whenever a Vehicle you control is blocked by a creature an opponent controls, put three tar tokens on that creature.
Metalcraft — As long as you control five or
more Vehicles, Vehicles you control
have "Crew {0}".
(A creature with tar tokens can't attack or block unless crewed. Its crew cost equals the number of tar tokens. Remove a tar token from it at the beginning of its controller's end step.)
