Because there are different timezones, we will have the following new rule:
If there are 5 or more wannabe challengers during the first 24 hours, we will have some kind of system to pick the "best" 4 ones. This is contrary to the first-come-first-serve system mentioned in the rules.
After this first 24 hours, if all 4 spots get filled, the 5th person must pick another element or become a substitute.
