Mercenaries

Please leave feedback on the idea, thank you!
I'm sorry but there aren't any pictures,ONLY DESCRIPTIONS if you have an idea for how they look be my guest to design them.
The mercenaries can be troops that you hire for gold(Because you wouldn't hire someone with elixir would you?) that have special abilities similar to heroes and can be each one has a 2 hour wait time before being hired again.
You can use one per battle
There are five mercenaries, Samurai, horsemen, assassin, Ranger, Ice Wizard(maybe called a warlock), and the titan.
