Th9 Farming While Maintaining Trophies?

[MalDux]

Hey guys,
I've been using ClashFarmer for some time now, and I've recently started facing issues while farming with my Th9.
I always drop to the Gold leagues from mid Crystal. (where I usually am.)
I don't want this to happen and want to stay in low-mid Crystal even when the bot is farming for me. 
I was hoping if any of you fellow Th9/experienced users could suggest me a fix to this problem. Wether it be suggesting a composition or setting tweak.
My current comp : 16 Giants 8 wb rest arch.
Thanks.

I'm giving this a try right now. So far, I have only done one attack, but it worked really well. Thanks for the tip.
