if ur just hitting collectors straight barch +wb is cheaper, as a bonus on weaker bases you can get the storage sometimes too.
If you want to 2 star it and get storages go with 15-20 giants, WB, arcchers
in either case id drop the healer and just bring a heal spell in addition to your rage using only when needed. heal spell especially for giant attack'
Your army set up is in btween both of these which I think is not a good thing.
Giant, minion, arch works well too especially for lix farming, but if ur going to use giants period,i think bring 12(15 really) is minimum, as the whole point of giants is to smash defense so ur t1 can get to storages, otherwise u can just barch to collectors no need for giant,.
