Flying
Whenever Mobilizer Mech becomes crewed, up to one other target Vehicle you control becomes an artifact creature until end of turn.
Crew 3 (Tap any number of creatures you control with total power 3 or more: This Vehicle becomes an artifact creature until end of turn.)
If an effect that causes a Vehicle to become a creature doesn't specify its power and toughness, it has the same power and toughness that it would normally have if it were crewed.
Mobilizer Mech's second ability triggers whenever its crew ability resolves, even if it is already a creature at that time.
That ability doesn't count as “crewing” a Vehicle for any ability that would trigger off of a Vehicle becoming crewed.
