Would have to playtest it through MWS, but I'm not sure a highlander deck is THAT much "testable" since it plays only 1-ofs. It's more of a fun format, so, if you have fun playing the deck, have a blast! I think perhaps YOU could pint out stuff that simply didn't live to your expectations in playtesting, and stuff you miss being able to deal with, so we can brainstorm on that.
