Wouldn’t it be fun, if there was another counter of elixir during the game like dark elixir from COC? It could allow you to put down different troops than the normal ones (they could have new special abilities or just be new cards exclusive to the game mode) or be really slow and allowing you to make disappear a troop that cost the same amount of elixir. It could be another game mode like goblin journey because it’s a huge difference in gameplay than classic clash royal. But I think it can be cool.
