TH9 Farming strategies

I have been trying various farming strategies in the past week,some created by my experience and some copied from the internet but none of those strategies seem to get me to the storages.

Which strategy is time/cost efficient and provides access to storages?

I used Queen Walk but it is focused on DE and provides very little elixir/gold profit.I tried Gibarch but I am not able to distribute the army as I tend to take some healers with the giants to avoid usage of spells.

Extra Question:If I use GiBarch with healer level 4,how many healers are sufficient?
