barch works just fine. head to c3 where you'll get a league bonus that will cover your army so you don't have to even look at the gold or elixir. start hitting any th7 base holding 750+ or th8 holding 1000+ with its de storage no more than 2 walls deep. take any snipes to stay in between 1900-2100 cups and get the de league bonus. also look for any th9s and th10s with full exposed drills. you'll probably lose the raid but the 1800+ de just from the drills is worth it.
that's how I maxed my bk10 and th8lab first time through before the update that gave th8 another drill and gave th7 a drill. doing the same thing again on my mini account and it is so much easier this time around.
