EDH with Teferi, Mage of Zhalfir as general. This deck actually began as a Memnarch deck, but due to several other people in local Meta having decks running the same General I converted it. Which also means that I shed a few artifacts as well.
Plays like a true-blue player...play during your opponents turns. Leave mana open for counters, or flash in creatures. Win-win.
If your commander is Teferi, Mage of Zhalfir you should run Knowledge Pool it's a combo card with Teferi, Mage of Zhalfir example: once you imprint with the artifact your opponents cards get exiled then go onto a stack, once the stack resolves your opponent then casts that spell at instant speed (weather it be creature, artifact, enchantment, plainswalker, sorcery or instant) and because Teferi, Mage of Zhalfir only let's them cast (from there hand) only at sorcery speed they can no longer cast anything but flashback and other cards along the lines of Gravecrawler . And it's perfect because you can go turn five, flash in your commander, then on your turn 6 cast pool of Knowledge Pool for game. And it's easy search. Use cards like Fabricate and Treasure Mage
