TH7 no BK, followed some guide on youtube that included BK. Tried it without, failed twice and 3rd time it worked out. If i remember right it was 2 rage spells, 1 heal spell, 30 ish giants, 1 dragon + 1 dragon in CC and few arch and wb's to break the top walls.
I used this same method, got it on the 3rd try I think.
