I Propose 3 New Ideas - Spell, Defensive Object, Troop

With the introduction of dark spells I would like to propose a ZOMBIE Spell. This spell would temporarily corrupt surrounding enemy troops/King/Queen caught within its radius to attack against their base.

Type: Corruption
Target: Enemy Troops, King, Queen
Cost: 1,200 dark elixir
Duration: 25s
Radius: 5 tiles

Secondly, I would like to propose a new defensive object - Stationary Storm Clouds (2-4). These, like tesla towers would send out bolts of lightning strikes. Unlike tesla towers, only air based attacks can destroy them.

Targets: Any
Range: 4 tile radius
Damage: 18
Hit Points: 120
Reload cost: 35 dark elixir

Lastly, I'd like to see a new troop; perhaps one that would take up enough space to fill a maxed clan castle. Maybe like a Rhino Rider or a Kong-like Gorilla that can plow right through walls.

I'd like to hear some feedback, maybe extend on these ideas like strengths and weaknesses?
