Let's keep it simple
Paper Rex were gonna be the last team drawn but they had to be in group D due to Riots rules
Then they had to organize between Kru, TH, and BLG
KRU could be in group A or B
TH could be in group B
TE could be in group A or C
They had to put TH in Group B
And since TH was in group B, Kru could only be in group A
As a result, Trace was put in Group C
