Ellivere of the Wild Court Virtuous roles can get out of hand quickly, so it makes sense that theyre limited to the Commander deck headed by Ellivere of the Wild Court
Even outside of triggering our payoffs, having a bunch of card draw is pretty powerful, letting us dig through our deck for removal and threats and making it super hard to flood out since, if we happen to draw too many lands, we can always discard them to Thirst for Discovery or Tainted Indulgence
Unlike Rhythm of the Wild or Delighted Halfling, this is a land thats obvious, but lands are significantly harder to interact with than other permanents that make your creatures uncounterable
WOTC has also been clamping down pretty hard on their dissemination
Putting counters on lands means you can use cards that animate lands, while Black Panther itself lets you move counters around and gain life
There's also a blue version in Propaganda for decks that don't run white mana.
