1. Using Hidden Teslas at the corners
In the video below, you can see that the player has a hidden tesla at one of the corners of his base layout. This can prove effective some times in cases where time becomes a crucial factor. One fact of this trick is that, the game designers seem to have programmed a fail safe wherein the tower is automatically triggered as soon as the TH is destroyed. But could come in handy.
2. Ensuring that your TH is the last building destroyed.
This was the second base in the same war as above and this was the base that I attacked. It was a last base and usually the last few bases cant do much except use cheap tactics such as delaying bu putting High level storage buildings in the corner or fill your cc with units such as giants which can keep the attacker busy killing for a while. So unless the attacker pays attention to this, he could be caught sleeping.
Well this one, I should say, initially we though was a funny base but ended up being a smart one. His idea was to surround his TH and TH only with all his walls thus putting a safe distance between the TH and the other buildings.Mine being a balloon attack, ended up getting 3 stars on this base but if was not careful, could have easily messed it up by not clearing the outside buildings and camps thereby luring the balloons away from the TH.
