Outside of this, I'd consider
Na'Vi *If they can get some better pickups (-Edward +Hobbit or +AdreN or something)*
French Mix Team *Doesn't particularly exist yet, but Vitality is the closest, I feel an immiment shift in Vitality or G2 soon so we'll see, I'd say if Vitality did -RpK for +kioshima (kio goes IGL, NBK goes support), and -Happy +AmaNEk or +to1nou (Depends on what they want to do) then they'd really be a contender for it, I only mention this because I feel an iminent French shuffle of some kind soon, and hope they can pick these players up, I wouldn't comment if it couldn't happen)*
FaZe *They'd need a good IGL (gob b, MSL, etc.) and they'd be a contender, honestly feelsbadman*
I feel like these things would be the top contenders for taking them down.
