This is one rumour that should be converted into reality. Clash Today would love to see something like this.
This trap would be activated underground to counter Miners, forcing the Miners above ground to fight.
In addition they could help destroy Bowlers as they would be activated by the Bowler and appear behind the line of hurling rocks.
More Barbarians would be activated higher the level.
What do you think? Would you like to see a Barbarian Trap?
