Haunted House - Set inside a haunted house. The battle is set at night time.

The main gimmick of the Arena is the continuous spawning of Bats and Skeletons from the towers. The four Princess Towers alternate between spawning a Skeleton and a Bat every 2 seconds, while the King's Towers alternate between spawning a Skeleton and a Bat every 1.5 seconds, in addition to all six towers doing normal damage. The King's Tower does not need to activate to spawn troops.

The timing of their first spawn is random (it can be up to 10 seconds after the match starts) but for any pair of towers (left towers, right towers, King's Towers) the two are synchronised. The gimmick of the Arena makes single target troops rather ineffective, however splash troops that can hit ground and air (such as Witch and Executioner) will shine here.

I can only think of one card to add here:

Spooker: A troop that spooks enemies, forcing them away from it. It's an Epic card costing 4 Elixir.
