Idea:

Want to know how effective your base design is? Test it out against any troops you want.

For a fee of 100,000 gold AND 100,000 elixir, test your base against any army you put together.

Re-spawn time for using this service is 30 minutes. (Negotiable)

Pros:
- You get to see effectiveness of your base design
- You get to see some of the newest hottest troops out there.
- You can practice attack formations and strategies

Cons:
- It costs 200,000 combined.
- While you get to use troops past your normal TH, you cannot change the current level of anything in your base.
- You are limited to the amount of troops currently available in your base (Negotiable) (200 troops available to you? That's all you get to use)
- Any base changes made to test are not temporary. You will need to re-design your old base if you do not like the new one.

I didn't see anything on the Sticky about this, but if it has already been ruled out, please accept my apologies.
