[Town Hall 11] Two strategies for 3 stars against max TH11
1. Giants + Healers + Hogs + Bowlers in CC, also known as HGHB

The trick here is
A) to start attack so that you can take out as much as possible opponent's a) eagle b) queen c) CC + good coordination on dropping hogs.
and
B) always drop first giants, then healers, then Grand Warden; use the wizards and baby dragon to funnel/clean buildings around the entry point; drop King, Queen and CC once giants break the wall and funnel is ready; so that you can drop rage on all troops inside; if you don't funnel properly, you risk King, Queen and CC go around the base
2. Full Bowlers + 6 healers

These are both fresh attacks I did about 4 hours ago, in our last war.
Enjoy!
