When u r upgrading a troop for example The barbarians to lvl 5 train as much as u can so ull have full army camps with lvl 4 barbarians and when the army camps are full fill ur barracks with lvl 4 barbarians which are 80 elixier and when the upgrade finish the price will be 100 elixier so if you remove them from the barracks ull receive 100 instead of 80 elixier and ur army camps will be lvl 5 barbarians instead of lvl 4 ones so ull have extra elixier and u can do this for expensive troops like pekkas and dragons so ull save a lot elixier ... Thanks
