I don’t think dr strange is actually him I think it might be misterio because in infinity war the thing that holds the time stone was destroyed but in the new trailer he has it intact also his actions are not like him dr strange wouldn’t cast a really dangerous spell without looking at the outcome
that’s true...however after tony dying, strange was really sad. he knew tony loved peter so maybe he did what tony would of wanted him to do? it’s a good theory though!
