War Feature - Preparation Day and Opponent Clan Castles
When you click on an opponents war base clan castle during prep day, you can get a view of how many troop space has been filled at that moment. That is a clue into what troops are inside. For example,
An instant increase of 20 troop space suggests a dragon, and rules out a lava hound. A bump of 28 suggests 7 wizards. Etc...
If it is simple to do, Supercell should hide the amount of troop space in opposing war clan castles during prep day.
