World Playoffs Group Stage Tiebreaker?
 

I was curious if anyone would know what the tiebreaker would be during group stages?

For example, if in Group A the results were:

AZF: 2-1
CLGP: 2-1
iG: 2-1
SK: 0-3

What determines which 2 teams would move on? Better not be random drawing LOL.

Please no flaming on picks, this is just an example group stage result.

Thanks
