First i picked the 7 to qualify, so :
Nip Fnatic C9 Avangar Vitality NRG ENCE
Then i pick ViCi for 0-3 because everyone did that haha. I know Grayhound and G2 have zero chance to qualify.
All that is left is Renegades, Vega, Winstrike, Tyloo, Furia, Spirit. So now ez. Spirit sucks, Vega upsets teams but never goes 3-0, Winstrike sucks but not so much to go 0-3, Furia are a new team which will get rekt in bo3. So between Tyloo and Renegades i picked renegades because they looked super good in the minor, they have been bootcamping in Poland and i also like them. So 50% luck 50% logic.
