My idea is theres a new area, open green field that is called the clans land, in which once the play unlocks the clan caslte at their home base, joins a clan this becomes available to them, this area would work much the same as a historical castle, defending against seiges and providing a trading point, outside of the main base, as the clan gains experience in clan wars it in turn upgradeds the castle, though it would see no direct use in wars or other events, unless u made that its own league, but as the castle increases in leave it allows players to unlock new units available at their home villages if their home Caln castle was high enough level, adding a new training ability to that aswell, the new units would be ones we see in clash royal or other, and no real advantage, but allowing a shift in the meta, another ability of this castle area could be trading hub, were u can store elixir and gold and clan mates can request of x amount and clan leader can approve, same with troops that say (eg 500 troop space) and any member can donate to it and any member can request from it, allowing people to have that donating ability when others my not be online or dont want to pay for gold pass and contribute to the castle instead.
