After studying Astralis' Overpass for weeks, as they themselves said, then went and beat them in a best of 1 (on Overpass). 3 of MiBR's players showed up and not a single Astralis player showed up. Magisk who is arguably their best player went 4-17.
THAT SAME DAY they lost two other matches (Liquid and FaZe). None of the Astralis players showed up in the FaZe game, and in the Liquid game, Magisk was the only player to win aim duels, going 27-18. When Gla1ve is sitting second on the team and being one of the only two players going positive, you know they're not on.
