[IDEA]: Special Campaign for Clans

Developers can plan for a special campaign especially for people in a clan.

Idea
The campaign can be in the form of a uber powerful base and it would require the cooperation of clan mates to take down the base. One clanmate can attack at most 2 times. Clanmates will need to plan together on how best to take down the super base.

Reward
The rewards can be in the form of gems depending on the percentage of completion of the campaign.

Rationale
Currently, only the top clans can vie for gem rewards and the many small clans are left out.
This campaign mode can motivate smaller clans to fight for gem rewards and also have some incentives to play for. (other than resources)
