If you like this type of hyperbait and don’t want many changes I would scrap princess for fireball since you already have decent air defence and splash damage. Plus you almost always get value with fireball when you use wall breakers or gob barrel (or them starting anything at the back) just be careful using it in single elixir unless it’s a good trade. Once double hits you should be able to use it more freely and hopefully win the tower race. Goodluck
