NRG vs KOI (the core of a Champions finalist team without their best player and controller vs (perhaps) the biggest dark horse of the tournament)
PRX vs C9 (a top 3 APAC team vs a team that has been shrouded with doubts since RBHG)
FPX vs KCORP (two of the most clouted teams in their respective regions)
EDG vs 100T (a VCL-less team back for another international appearance vs the team that has been making a lot of noise as the Americas' best)
LEV vs ZETA (the LATAM superteam better than ever and a possible top 3 Americas team vs the clouted team that has won the hearts of many but made no changes to their active roster and have a lot of doubts surrounding)
SEN vs FNC (at least two of the contenders (on paper), and one of them is making to the second round)
