0 hero 3 star

I tried last war with 0 heroes and used lightquake lavadragoon for both, one got me 0 stars (drags wandered and didn't kill queen) and the other was a 2 minute 3 star. I used drags to do what heroes normally do (kill queen and cc) then had 3 lava hounds and 16 loons with my 4 drags. The queen was decentralized and the cc was lureable, and ads spread.

Anyway just wondering if others have polished this strategy a bit because it seems powerful and very strong against the right bases. The first attack I only lightquaked 1 ad, the second time I took 2 out. 2 ads at th9 is incredibly easy to deal with.
