The giant wizard strategy is a very good cheap trophy pushing strategy. Although i'm writing this for TH8, you can use it at any Town hall lvl. heres an example vid: https://www.youtube.com/watch?v=vUTHcf_eCUM
Army composition: you can adjust it to work better for you
20 giants
16 wizards
6 wall-breakers
1 healer (optional)
fill gaps with archers
Use: start by finding a good path to the center of the base. place giants accordingly to take hits from defenses and wreck defenses. use spells with giants to help them either wreck defenses or keep them alive. when the giants are placed and splash fire is on them (or soon to be) lay the wizards. with the fire on the giants with them taking defenses, the wizards can go in and destroy the base getting you at least 1 star most likely 2 possibly 3 depending on the base and how well you attack.
