有人說LMS的找隊伍的方式很鳥，所以我特地去翻了NA/EUCS的規章來看
以下擷取自NA/EUCS的規章(發布時間今年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.
紅色的地方我稍微用我粗淺的英文翻譯來看是說
該隊伍必須在限定時間打到伺服器前10(而且限定菁英)，才有參加挑戰賽的資格
後面好像有提到篩選隊伍的機制，但是本人愚鈍有沒有人能稍微解釋一下
