Howdy!
Firstly- over time,I've tuned my Karn deck to be more fun (for my locals to play against) and less competitive. Feel free to check out the list and comment wherever you like.
Secondly, I'm unsure if I fully understand your question - does your competitive group allow you to use Karn's planeswalker card as a Commander despite it being banned as a Commander (because it's not a legendary creature)?
If you're using Karn, Silver Golem then you might find my list somewhat useful. If not, then the Silver Golem / Voltaic combo might not be worth including. If you're allowed to go the planeswalker route (and your group plays with mulligans that would allow your deck to flourish), I'd imagine it would more resemble Juwdah's Kozilek list with a ton of ramp - and you'd add some elements to keep Karn alive (like Forcefield and Portcullis).
