The problem with the Supreme Court is the handshake-agreement to limit the court's size in combination with lifetime appointments and the Senate majority leader's pocket veto. Going back to 1992 (eight Presidential terms, three served by Republicans and five by Democrats), Republican presidents have successfully nominated six justices while Democrats only five (including a no-vote for Merrick Garland).

The better thing to do, in my mind, is to limit the term length of a justice and eliminate the pocket veto, but I can't think of any way in which the elimination of a pocket veto also can't be exploited in some way (eg: with a 6-3 court, if a Republican-aligned justice stepped down, a Republican president can knowingly put forward a candidate they know won't get approved to keep the margin 5-3 vs. 5-4).
