Warbringer Minion build help

New League and I'm interested in resurrecting a 0.1 build with buffs to warbringer. The unfortunate part is I've never been a theory Crafter. I planned on initially following the build and changing supports as I saw fit to the best of my ability but half the gems are unavailable.

I'm also lost with the ability to socket the same support more than once.

If anybody has the time or desire to help a scrub out with a look over this is the build I'm trying to do:

Cheers, and thank you

Even just some ideas of supports would be spectacular!
