Barb/Arch Combo, how to use it?

Alright so I've seen alot of people talking about the barb/arch combo and how it's effective and I don't know so that's why I'm asking. Why is it effective? Obviously it's effective in cost wise and time wise but how do you manage to destroy the village without wall breakers and giants? Like I always use breakers and giants but how do you deploy your barb/arch army? What goes first? Do you deploy them all at once or in groups? How many barbs and archs should I use when I have an army number of 190. Do you use spells to help your army? If yes, what spells do you use? If you have heroes, do you deploy them with your army? I'm asking all of these questions so I can at least get an idea of how to use them. Well that's what a Detective is gotta do to find his suspect :)

I have asked a similar question before and got some good advice here .

i think just spread the barb first followed by archers. hope it will help :D

Its very effective but not on purple walls or higher. First clean up all the buildings outside walls with a small amount of barb/arch. Now. when they start hitting the walls, spread deploy the barbs to confuse mortars. Then deploy a groups of 10 to 15 barbs in 2 to 3 corners to focus on hitting a wall! Archers must be deployed timely! they will take out the buildings fast if deployed well to focus on targets behind walls!

Actually, if you bring the right amount of wallbreakers (8-12), Walls don't mean a thing to this combo at all. I've destroyed and 3 starred a lot of purple and black wall bases with mass barb/arch combo.
