Battles inside ones own clan.
So bascily what this is, is that when your in in clan you can attack your clan mates but you cant cant gain anything like no trophies or gold, exlier, or dark exlier. Anyways what this will be able to do is that when your clan mates attack one, you can watch the replay and i think this might help people because they can watch the replays so better training for clan wars and how to improve your base. that way u can see how your clan mates fight and with the new update this will help the clan leader al ot so they know how there attack force is and who to chose to take into battle.
