Obuun, Mul Daya Ancestor has made less of an impact, as there are generally more interesting and powerful commanders in their colors
Or perhaps even if they are, they know from experience that it doesn't win them any friends on game night
In Commander 2016 , the typical deck has at least a couple of lands in the $5 price range
It was very good and super interesting because you could turn any creature into a grind engine
I love this in the 99 of aggro decks like Boros Aggro, or goad brews that want to force attacks like the first one for triggers, or cast from exile triggers like Rakdos's Prosper, Tome-Bound or well, you can see the synergies, card flow and forced attacks this little boy can do and he drops before real counters are on line or are immune to them like Swan Song or Negate or An Offer You Can't Refuse
When Teval attacks, you mill three cards and ramp, and when cards leave your graveyard, you make a 2/2
