Thats one of the most used attack strategies. On youtube, look up balloonian attack strategies. You see really good ones. And upgrading to lv 5 minions isn't that hard. It's more commonly used for trophy pushing, but can also be used to take away lots of loot at higher trophy counts. But at 1800, stick to BAM for mainly farming. (Barbs, Archers, Minions) Good luck!
