A new kind of trap: Invisible walls
Invisible walls would be kind of like a way to distract wallbreakers or any other of your attacker's troops. Once troops come within 1 tile of an invisible wall, it will appear. If a wallbreaker accidentally runs into one (it can't see invisible walls until they appear), it is forced to explode and destroy the invisible wall. Also, if other invisible walls are within the wallbreaker's detonation range but haven't appeared yet, they still get destroyed. I'll let you guys discuss how many of these you can have per town hall, to avoid being criticized for making them overpowered or too weak. Thanks if you read this and comment below on what you think.
