Town Hall 7 is a great place for trying various kind of attacks as you will have many troops and spells in your hand in this TH level. New powerfull troops means more attacking options. The freshly got troops such as Dragons and Hog Rider are really a game changer. I have already written a post on how to use Mass Dragon in Town Hall 7 and 8. Today I'm going to show you how can you get 3 Star in almost any Town Hall 7 base by using Mass Hog Rider attack.
Though Dragons are the most popular troop in TH 7 and 8, but in Town Hall 7, if the base design is too complicated, you probably cannot get a 3 star by using this strategy. So for such bases, you should have prepared another strategy for attacking TH 7.
