I am participating in a project i called "Game of Thrones"

We pretend that we are a team, but in reality everyone hate one another.
It took only 3 weeks for Team Leader to turn everyone against him.
He is constantly fighting for power with Architect who is terrible at his job, and doesn't listen to his advice even if they are good.
We hate Team Leader because he is an tyrant, who is ruling from high tower his peasants. His favorite task is to create various rules that everyone has to accept. You have to write "I accept" in a chat but this is the only choice. You cannot disagree.

Moreover there are developers from client side. They "committed" current project which is full of bugs and generally doesn't work. I don't know why they are still working there, but I presume every of them is working for 5+ years, so they are the only ones able to dig thru the spaghetti they made.
They constantly fight with us about the how code should be written, they commits are garbage but they are very peaky when it comes to ours PR.
They always drag our PR as long as they can. Even sometimes pointing they mistakes as ours.
