Clan internal tournament

Basically the idea is to periodically (ideally at the start of every season, so roughly every month) start a tournament inside each clan to decide who's the best player and assign a rank based on the results coming from that(I thought getting inspiration from the chess, so King for the winner, queen for the finalist, and so on..) that'll be valid for the whole season.

Basically at the start of every season the tournament will start with all the player inside the clan at that time.
They'll face one against the other in a knock out eliminatory style phase (my suggestion is to put the one with less trophies vs the one with most trophies and so on). Any player will have the same availability of troops and level of buildings/base and will be able to decide what to put in the castle.

For this purpose, there'll be another tab to prepare the war base for this tournament (same way you have a tab for multi and war bases).
Each day there'll be a knock-out stage. I guess it would last about 6 days at most, depending on how many members are in the clan.
If you leave the clan to join another you'll loose that rank (unless you come back to the same clan in which you gained it).
This should also improve loyalty to a clan and less hopping.

The victory will be determined by who get more stars, and if on par , by who get higher destruction rate.

This idea takes inspiration from medieval tournaments where chevaliers from the same country used tournaments to measure up who was the most valorous among them.

Same I guess many players would love to measure up against their clanmates on a fair ground lvl.
