Making Bermuda Triangle at Soulkeep

I have made Bermuda Triangle in soulkeep with spells and towers as in the first wave of level 5 which is last level of league 1 I want to use the map well and the ways that fiends will come from to make this triangle which when fiend come in it so it will never come out.

This is what I called it Bermuda Triangle that consists of 3 towers and also 3 spells which is like a 3 angles that fiends which came from two ways will pass from it and this will be a good trap that fiend will expose to hits from three positions at the same time.

First tower I have used is Card Sharp which is a strong tower to be used with a magic attack and good range that will make fiends destroyed in such few seconds and with a stew of doom spell that with its magic explosion will help this tower as it is near it.

Second angle which also consists of tower which is knife trosser and a spell which is raining cats and these two will also help in eliminating fiends that came from two ways also as physical attack of Knife trosser and also good physical damage of raining cats.

Last angle of this trap was Jack Joke and with a good spell also which is Cracklesnap and it also help with other tower to eliminate as much as fiends of this wave.

Finally I was able to pass a wave and this strategy was amazing and only one fiend able to escape from this triangle after spells has been used but more than 25 fiend was eliminating thanks to this strategy and I was able to save one spell which is Cracklesnap and the remaining has been used in destroying the fiends.
