I know DRX are playing very good, but so is the rest of the teams. So their only chance is to win over Sentinels (very possible) in the opening match
Leviatán and Trace
No way Leviatán wins against G2, and when they lose, they'll have to face Heretics, a match that they will also lose
Trace will lose against EDG only because it's a regional match, if they lose, they'll either face Sentinels or DRX, and I think that both of those teams are favored against Trace
