Is MiBR good?

I decided to go back and watch the entirety of their match against TH. They played quite well on Corrode, especially how they took mid control really frequently on attack. It looked like they had a very good understanding of what they wanted to do, and Artzin had a life map. On Sunset, TH played like absolute garbage, while MiBR played fine. They didn't make any terrible mistakes but also benefitted from TH trolling (especially Boo).

I can't tell how good this team is because they seem to be playing pretty well, but in the 3 games they won their opponent played disgustingly bad.

they made their opponents look bad by playing good teamplay wise

yes, they are the best team in the world

if artzin keeps up, they can definitely win

bro of you are too good your opponent will look bad, just look at g2 vs t1
