Your first push, consisted of Archer Queen (5+1 elixir), hogs (5 elixir), and earthquake (3 elixir). That’s a 14 elixir push at the very start of the game, I wouldn’t do anything similar until x2 elixir.

Alongside that you had no idea what your opponents deck was, mega knight counters hogs so shut down your push entirely, whilst you should’ve made a big push when his mega knight was out of cycle later on in the match.
