GiWiBaArch is a strategy I invented and I use for gaining trophies. The GiWiBaArch strategy is for TH 5-6 and Silver III to Silver II.
It consists of: 5 giants, 10 wizards, and the rest%50 Barbarians and 50% Archers.
The order of deployment is: First, swarm giants near a mortar. Second, spawn archers and barbarians around the edge of the base. They should take out the exterior buildings. Then deploy Wizards if necessary. This should give you at least one star.
