Artifacts can be some of the most broken cards in the game because they are not bound by the limitations of the color pie. The right artifacts can help different colors achieve things that specific color was not designed to do or help to push a color into the realm of ludicrous speed doing what that color was designed to do, but all of that is a different topic. Right now let’s look at some of the cheap artifacts you may want to consider running. Ramp is always a must in commander and yes, you want Sol Ring, Mana Crypt if you can afford it, Izzet Signet, Arcane Signet, Talisman of Creativity, Manakin, Hedron Crawler, Palladium Myr, Iron Myr, Silver Myr, all of that good stuff. If it can produce mana for a relatively cheap casting cost, you probably want it. You can also use Urza, Lord High Artificer to in essence turn each of your artifacts into a mana rock.
