It is nearly impossible to stay below 200 trophies. unless you are <th6, it will take less than 20 minutes(on a slow day) before you win enough defenses to have over 200. People will attack you immediately after you log off and drop a barb to lower their trophies. you will win that defense, then it will happen again.
You can try it yourself. Go to 140 or so trophies and watch them slingshot back up. I have a th9 that I try to keep at 400 trophies or so. I have to lower my trophies about once a week because I creep up to about 750. And this is with my th outside and undefended/not trapped.
I bet that all the th6+ dead bases are around 600-800 trophies.
