Right away do the lab, CC, and spell factory. You can do those three with what your storages hold. Optionally add new traps.

Then target elixir so you can max all four camps. Use dark elixir in the lab during this time (max golem and/or hounds).

After you finish camps, CC, and some troops maybe go ahead and add the cannon and archer tower.

Don't add the third xbow and certainly don't add infernos until you have developed your offense and can 2* low (but legit) TH10's with infernos in war. I want max golem, wiz, WB, and 4+ freeze for sure before adding infernos. Not sure on pekka but maybe max pekka for max gowipe then add infernos.
