Thrifty Joker (A New Hero, for Farming)

So far Clash of Clans has three heroes, a King, a Queen, and a Warden! So doesn't it make sense that something like a joker should follow? I don't quite have a picture, plus I have no idea how to do graphics, but I hope the ideas I have for this hero will work just as well. He should be used mainly for farming purposes, but can be taken into war. When you pop his heroic ability troops in his aura (much like the grand warden's aura) will gain an increase in the amount of resources they can steal for a certain amount of time, let's just say for now they are able to steal times two the normal amount of resources for ten seconds. However, the joker's health is relatively low, and his aura is short, so you need to make sure you can get him in the most profitable location for you and your troops, without having a defense destroy him. His passive aura could maybe even boost goblins' attack power, because, yes, I know this sounds a lot like a goblin king, but that is not what I think anyone would want in the game at the moment. At town hall level eight upgrades really start to stack up, so I think that would be a good starting town hall for him. While this would also break the "every-other hero" pattern Supercell has implemented, I believe it would also help with the balancing that they said they would get to in 2016. Please leave feedback, and feel free to take this idea and make it better! I am by no means an expert on this stuff, but I know other people are! :-)
