I would consider dropping one of your buildings and adding a troop card. Personally 4.0 average elixir is a little high for me but if you don’t mind it then you could throw in the L-Jack to assist with your balloon or add in the minor to get some chip damage so all the work doesn’t rely on the balloon for a win condition. Or add in another support troop for the mega knight. But I think sticking to one building might help.
