Best attack strategy for TH6

Please provide the best attack strategy for Town Hall level 6. My troop capacity is just 140 and Clan Castle capacity is 20.
I need some effective strategy for clan wars, so that it can three-star other town hall 6 bases.

Thanks! :)

1 healer
3 wall breakers
15 giants
25 archers
20 barbarians
:D

all that and request a second healer for your clan castle. I'd even go 12 giants and make up the difference with 15 archers. I also recommend 2 well timed heal spells and NOT to use lightning with the giant/healer combo.

I am a completely maxed TH6 with150 slots in my camps and I usually use this strategy, but you have to wait 1 hour between raids and it takes a good bit of elixir. But it is good for loot and will 3 star almost any TH6 and below
15 Giants
10 wizards
4 balloons
1 healer
1 barb
2 lightning spells(for mortar)

You have to wait but if you find the right village you can make a big profit
