Again, Article II of the us Constitution says that the President has the power to nominate appointments to Article III judgeships. That nomine is then conformed by the Senate and is then in that post for life. The only way for a Judge to be remove is by Impeachment and that takes 2/3 vote from the Senate after an article of impeachment has passed the house. A President can't come into office and start firing judges even with an executive order it is not with in his constitutional power. If this were a power that could be wielded by the president don't you think that Trump would have used it by now? It not about playing a game at all it is the divided power of the government set by the Constitution.
