Possible Idea: In-Clan Tournaments
This would be possible, and could bring back some people who left because Clash became too complex and boring with recent updates.
With In-Clan Tourneys, it would be like a war, but only with one clan. There would be win bonuses, and prizes for getting a certain amount of stars (e.g., 5000 gold every 5 stars). It would have no prep time, but bases could be modified until the person has been attacked once. It would also help with designing new strategies and bases.
I have discussed this with other members of my clan, who agree it would be a more fun way to get back what we lost with the recent updates
