Team HawkeyevsTeam Proxima Midnight

Team Proxima Midnight Proxima and Corvus already beat Hulk and Black Dwarf fought Super Skrull, Gladiator, Annihilus and Ronan at once

Team Hawkeye @RatnikNaSjeveru2005 Black Dwarf's fight with those didn't go very well for him.
Gladiator one-shot his weapon.

Super Skrull, who has the strength of the Thing, could match his strength.

Ronan then one-shot him.

Thor should easily be able to take care of him. In fact, Thor can arguably solo this group. Even when unworthy and imprisoned for months, he could defeat Black Swan and Proxima Midnight.

He is resistant to far higher levels of mind manipulation than Ebony Maw or Supergiant can use.

He's just more powerful than anyone the Black Order can defeat.
As for Hulk, he generally scales above what was displayed in that storyline. Even if that encounter is identical, it buys enough time for Thor to defeat the others, and Hulk still has support from Iron Man and the others.
