Skullcrown should be build for pure damage and campaign farming.  

You need gear, dragon 20 should be your next goal.  You will likely need the 3 support champs to get there.  Eventually, as your gear improves you will likely only need 2.  These will be slow runs, lol.  But you should be able to clear 20 at 100% in a week or so.  Plan on running multi-battles over night in dragon for the next month or so :)
