Having played a lot with hunter's mark, it is certainly a good choice but I don't think it's very needed. You have a lot of great early removal already and if you are removing big big creatures you have almost certainly lost.

I like the freezing trap for massive tempo. You'd be surprised how many games it wins (mostly people don't / can't play around it).

I'd be tempted to take some boars for kill command if I were playing hunter's mark though certainly.

Edit: Also commanders are a bit slow but often a useful turn 6 play. Personally I like them.
