For the last many matches I have faced much higher ranks than me
It's been like 40-50 matches I get matched up with high Gold, Plat and from time to time Diamond.
And I am not at that level yet. Even if I am unranked, I would say my MMR is Silver.
Just last match 600k D4 Katarina. She went 23-1, solokilled Yasuo 4 times in like 10 mins.(B1 Yasuo btw). The most fun match of my life.
Tried with a friend that has Plat MMR, tried with my brother, who is B1 with B3 MMR. I didn't matter who I match-up with, I still get much better opponents than me.
Sometimes I can outplay those much better players, like when I destroyed a G2 600k points Thresh with my 4k points Blitz, but most of the times I lose cuz of the stupid matchmaking and it's frustrating.
