ok, since he doesn't have lots of health, another way is to distract him and let the princess tower kill him. tombstone will work as the hunter will need to constantly stop to kill each skeleton.
Goblin Hut is even better at that. Spear Goblins actually outrange him since their 5 meter range is longer than his 4 meter one. Also since they spawn quite fast, they can distract him for a long time, while the Princess Tower fires at him.
Unfortunately, this does not work on the opponent side.
but this will result into a negative elixir trade.
