有人说LMS的找队伍的方式很鸟，所以我特地去翻了NA/EUCS的规章来看
以下撷取自NA/EUCS的规章(发布时间今年3月22日)
For a team to be considered eligible for the Challenger Series:
the team must be in the top 10 of eligible teams in the
Challenger Tier on the Ranked Teams ladder at the time of the deadline;
and the team must be visible on the Ranked Teams ladder.
CS officials have the right to deem a ranked team ineligible if there
is a reasonable belief of impropriety.
Conversely, CS officials have the right to deem a ranked team eligible
if there is a reasonable belief of extenuating
circumstances that compromised an otherwise eligible team.
红色的地方我稍微用我粗浅的英文翻译来看是说
该队伍必须在限定时间打到服务器前10(而且限定菁英)，才有参加挑战赛的资格
后面好像有提到筛选队伍的机制，但是本人愚钝有没有人能稍微解释一下
