What about a new ghost pirate (with no damage & strong defense?) to fool the towers and allow other pirates to destroy?
If it were a ghost pirate then it once would have been a real pirate all be it in a digital made up reality but that being said, it cant actually be a new pirate if it were a ghost pirate. We could conversely create a new pirate and then kill it making it a ghost pirate! But then that would be wasteful because if you created a pirate why would you kill it? How about a pirate that turns into a gun tower once you hit the button? Seems fairer 2 gun towers battling as equals!
