This land-heavy card spread makes a lot of sense given that the face Commander (Yuma, Proud Protector) offers you the chance to sacrifice land to draw a card and create creature tokens
if anything, Modern has just gotten more powerful to balance out the Looting
Even if your commander is small think Talrand, Sky Summoner or Emry, Lurker of the Loch you can slot in ways to boost its power to potentially draw you a fair number of cards
This list also uses some standard aristocrats pieces to get extra value out of the constant, inexorable march of death
Now, in the format I normally design for (commander), this doesnt change anything, because those cards still have a multicolour identity
Artifacts in general also play a huge role in Commander, with plenty of decks relying heavily on artifacts and artifact subtypes, so this deck does a great job of teaching a new player how the various artifact types work and how to make the most of them
