Sumail carry? I think he will take the midlaner position as in the previous team, I think OG is trying to resuffle all their roster, trying the best game from each player, it is not impossible that the sumail position as a carry will be replaced if it is not effective for him in the long run.
I think Sumail is good as a carry, currently OG is mixing things up between their mid and safe lane because they had some success with it previously like the mid gyro and it could be a good strategy to trick the enemy team. Unfortunately Sumail won't stay for long in OG he's only acting like a temporary replacement for ana since OG announced he'll be taking a one year break from playing competitive iirc.
I think one of the team will win theis game is the VP or Team secret because we all know the capability of the team secret or also known as the king of the majors because they are one of the team conquer the whole major from the previous matches they kicked off other players also VP has ILTW which is food at the core laning stage he gives a good chance to the VP to get this also from the previous match and ESL they've got the car with the MVP of No[one]. I'm looking forward to those both team. But wait there's more the alliance already kicked of the Team nigma where they do not have chance any more and also the Alliance has NickoBaby that can carry the whole game but the Team Liquid too makes a great move because the previous rooster of Alliance now in Liquid have a good mid laner. Sadly we cannot experience those high played skills player and teams for this coming international 10 of proscene.
