My strategy was to just 3 lightning spells on those bases with 3000+ which were pretty much impossible for me to raid as a th 7 and then also mass dragons on those with 2000- that i had a chance at. i was staying within the range of gold 3 to gold 1. I found this worked really well got my barb king to lvl 3 within a week and both my minions and Hogs to lvl 2 so its pretty simple no master strategy to it just a lot of constant raiding
