BEST OF LUCK MY FRIEND!!
Don't worry, you can do it! Those 200 cups, try to make them in 8 hours until server kicks you, that is the easiest way.
From crystal 3 took me 15 days approximately (based on my last defense win) as a TH7, I just needed to remember that there have beed TH3s who made it there before me.
Lolzlz I hope I am not in your revenge list though.
One piece of advice, the best time of the day to raid is from 6am EST-10pmEST
The easiest route for me was the 3150 zone, I lost less on defense by then since 3500 cup guys can already find me.
