What Not To Do In A Farming Base with a town hall protected by mortar:

In this case you probably might be using BARCH, Barb Arch Minion, etc.

With this you need to destroy the side buildings of the town hall so the troops will CERTAINLY go to the town hall. Then Slowly deploy barbarian archer. If you place them all at once the mortar or wizard tower will 2-3 shot them.

HOW TO BARCH. You are using only BARBARIAN and ARCHER. That is simple and the attack is way more simple. This is a farming composition so you would be searching for bases with loot closer to the outside of the base. Place the barbarian first for shield then archers for power. That said you will rummage through the base's collectors or some storage easily.
