2100+ are a quite impressive rating for sealed mainly, where some luck factory may be involved also Justice's 41-4.
I would like a deep answer how to get better/improve Sealed game if some top player don't mind write alot, now I just can't reach 2K+ rating or beat a good player with bad card set ( that's I guess it's the secret, how to play worst cards, if there is worst cards or just worst strategy), feeling "stuck" .
I also would like to leave a question:
Would it possible to always win by skill ? Like in chess or pro korean SC players ?
Possible but highly improbable
Since its sealed at some point you bound to get the worst possible deck on worst possible map against the worst possible deck opponent has and worst possible luck
With godly skill you could get about 10-20:1 ratio of winning but to win 100% of all times is highly improbable
This game fundamentally different from chest and SC since in chest you and opponent get same units while in SC you and opponent could pick your race and all race relatively even
But on sealed you cant exactly pick your card thus improbable to win 100% against good opponent with otherworldly card when on the other hand your cards is crap and also theres additional luck factor too like coin toss
However it's more highly possible to win 100% on constructed assuming you can use all card you want and your skill is godly
