Ideas for new Traps for great defense

Hi, I would like to suggest these traps for defense.

1.) A pitfall trap. Its trigger radius will be 2 tiles. Level 1 is to trap 5 capacity troops (giant is 5, barbarian and archer is 2, and so on). It will not disappear until it is full. The next level will add 2. Heroes can not be trapped here. This can be available for starting at TH8. Only one pitfall trap per townhall upgrade.

2.) A Flying achor. This trap will be used for large capacity flying troops such as dragons and balloons. Its trigger radius is 4tiles. It will fire from the ground and will hold the captured victim temporarily for 3seconds for Level 1, 5 seconds for level 2, 7 seconds for level 3 and so on. This will be available in TH 8 with 2 Flying Anchors. Place the Flying anchor near defense structures that can attack aerial troops.

3.) A Chain Net Trap. This trap is like the flying anchor that is used for flying troops, no exemptions, this is for any flying troops. Its trigger radius is 4tiles. This trap will drag the captured victim into the ground so that land defensive structures can attack on it. The chain net will disappear after 3seconds for level 1, 5 seconds for level 2, 7 seconds for level 3, and so on. When the chain net has been removed, the captured victim can fly again and can attack again if it is still alive. :D
