Captain of the Fleet

Whenever you cast a Vehicle spell, you may pay
X. If you do, Captain of the Fleet becomes a
copy of that Vehicle with X additional +1/+1
counters on it until end of turn. Whenever a
creature you control crews a Vehicle, that Vehicle
gains flying until end of turn. Whenever a
Vehicle you control deals combat damage to a
player, that player loses life equal to the Vehicle's
power.
No ship is to big or too small to serve the Fleet.
