When you reach higher levels (erm... 60+ ?), most players would have more than 200 DS so they'll be able to field their best def team all the time...By then it would boil down to choosing to attack the player with the weakest leader... And remember to use your crewmate backup everyday... As long as you can hold onto the stones you have, you'll have time to go out and get the other stones...

I pretty much gave up on the Katja stones... At lvl85, even if I do successfully defend against some players, a cash user comes along and takes it away eventually...
