OK, last math of the night xD.
FaZe is 1-1-3 right now with 6 points and CLG is 2-2-1 with 7 points.
If Selfless beats FaZe, CLG is in no matter what happens here.
If FaZe beats Selfless they'll have 9 points, and CLG needs a win here to get 2nd seed.
If Selfless and FaZe tie, then FaZe will have 7 points and CLG needs to tie here to get 8. If CLG lose it'll go to tiebreaks but it's impossible for them to get enough maps to win the tiebreaker in this scenario, because FaZe will be 12-12-0 on maps and CLG will have at most 9 map wins.
