This army will take about 26 minutes to train, giving you about two attacks an hour.
Another advantage, NO DARK ELIXIR. While gaining this gold, you will also see you DE Rise!
BEFORE ANY ATTACK Luer out any CC Troops and the opposing hero, kill them with spare Archers and barbs. Then go for the real attack.
You will want to attack by first taking away stray buildings with Archers. Next, do lines of barbs (Never put them in a bunch. After lining a side of the base with barbs, send in your few Giants behind them. Next, the wallbreakers. This creates a huge shield for Archers, which you will also put in a line formation next. Once the first defenses and wall layers have been removed, send in the Goblins to start cleaning up the gold. LAST, your hero who will get backup scraps to get you that 50% star.
