Battle of Britain

When this battle enters the battlefield choose a vehicle you control and create a token thats a copy of it.
Sacrifice that token when this battle leaves the battlefield. When this battle has 0 defence counters, exile it and destroy three creatures defending opponent controls.
I expect that the battle for britiain is about to begin... if the British Empire and the Commomwelth last for a thousand years, men will say "this was their finest hour."
Winston Churchill, June 18, 1940
