Parivision when I began watching their series in the DreamLeague Season 25 were undefeated 7-0 in this tournament.
But since then had loss to Team Spirit having issues with their finance balancing since they lost the first map due to not being able to buy back to continue on and had their base destroyed. It all went downhill from there.
They've been group stage merchants for quite a while, and the teams they faced in the playoffs also improved at the near end of the group stage, so it's almost like anyone's tournament to win.
You can watch them live on their official youtube channel below:
GamerLegion vs TYLOO - ESL Pro League Season 21
I'm shocked by TYLOO's performance so far, and I hope they make it through because beating EF and 3DMAX in a 2-0 fashion isn't easy for most teams. They're currently 2-1 after losing against GamerLegion and could be in the next set of teams to qualify for the next round if they beat MIBR.
