The drugwars spy is a good tanker!

I was attacked today and I lost all units.
When I checked the battle results, all my knifes were dead.
Your opponent is the only spy.

Spies are cheap, so they do not cost much to produce.
And even if attacked, the spy does not die.
But if you attack with Spy, you know today that Spy can be a good tanker.

If you attack, I recommend attacking with many spies.
