The advantage of this formation is that it is not short of money and labor-saving, and because there is no corn cannon occupying 2 squares, it can be protected by adding baskets. (Except the King of Thorns-)
The disadvantage is that I just got to level 40, and I have to pay the maintenance fee to the thorn king in the middle.
