I've been in this situation as well and there are no realistic options to improve it without leadership recognizing the manager's affect and redressing same.

> Micromanagement, lack of vision, poor communication, poor planning, zero support, full package.

This isn't going to get any better. More likely it will get worse over time as your new manager is under more stress to deliver on promises made, without the requisite planning and/or consultation with their team needed.

> About half the team share similar view. The other half seems like just playing along.

Experience suggests the latter group shares the same view as the former, but have other priorities (family, stock options, retirement, etc.) outweighing sharing them. This is not a judgement nor a bad thing. It just is.

> I still care about the mission and about what I do. Though not as much as before this all happened.

This is an inevitable transition resulting from this scenario. A cheeky phrase for this is "beating the care out of you."

> What would you do in my shoes to make the best of the situation?

Make as few waves as possible; do what you are assigned to do ethically.

Take your time to identify an ideal opportunity in another company.

Say nothing of the job search.

Only move on to another gig if you have an employment agreement in place.
