Build Angels

It would be cool if we could build the angels as a troop. I would suggest having them only in Castles.

The only issue I see to making them only in castles is it would only enable the people who can get a castle to have them and that would make a powerful player even more powerful.
Maybe make it lev 25 barracks. And like hk, need coins to get to that level.
Maybe something like 100 coins to get the ability to build them.
But also make it so players can earn coins in the game so players that don't buy coins can still compete. (See other post on that topic)
