This dealing with promotions things has the potential to be complicated and confusing. I think it's an adequate assumption to assume that all clans can promote equally with an equal number of practice, and so move about tiers is not necessarily needed. However, I think it would also work to have a re-shuffling mid season. I think any shuffling which takes place more often than that just has a potential for drama, confusion and delays come game night. Having a mid seaons shuffling also means that people who legit move from gold to diamond can be moved.

tl;dr - moving between tiers should occur at a designated time(s), to save confusion and make administration much easier.
