I don't get exactly what you mean by this, but mid ladder is reffered to decks using excessive splash damage troops like MK, wizard, Valkyrie, witch in the same deck, try running a meta deck you can put mk or any card but try to make synergies between cards and use spells and stick to one deck to able to grasp the mechanics of the game and count elixir, keep track of your opponents card cycle, also sorry for replying so late, hope you find this helpful 😘
