Anthropas Camp 10 my strategies

I've successively defeated level 10 camp with these troops linked down here:-

And these one:-

But at first place at my technique that used to march 3500 LJ + 300 Ats + Great dragon (Included or Excluded; it doesn't matter 'caz i never lost anything. But recently i started using LBM with LJs+ Ats but things neither went wrong; but few days, specifically 3/4 days ago i've lost my ats (300) while marching with LBM+LJ+ Great/Elemental dragon. Here is the result:-

And this:-

[Its to note that all my research is level 10 except Warrior revival and Guardian revival; but it doesn't effect the camp attack; further to include i've used FOCUSED ANTHROPAS ATTACK 5% that boosts up attack and defense of troops while attacking camps- for those who r not familiar with it] That's my story..... i never lost troops like this whether I've sent the City dragon or the Other guardian dragon or not. I've never used WinD or MephD; and will not use them in future to defeat camp; as u know they they r melee dragon rather than ranged specially Mephitic Serpent. I've heard attacking camp 10 is risky with LBM, but why now?... not at early stage, IS IT THE FACTOR OF PROBABILITY???
