I'd say try it in Ultra league first. If you like it there, keep it there. If not, go nuts for Master league.
You can go Ultra -> Master. You can't go back though. I get the feeling Machamp isn't strong enough for the Master league, but what do I know.
Pretty sweet legacy moveset you have on him though!
