This card works very well in Commander decks that dont let the mana empty from the mana pool, like Kruphix, God of Horizons, or cards that let you untap your permanents, like Seedborn Muse or Wilderness Reclamation
There are a number of reasons to call this massive new set a success, and the most obvious one for someone like myself that doesnt always have time to play TCGs but is perfectly happy filling binders up with shiny cardboard the art
It also does so while being a nice safe high value play even when from behind
The mono-color Partners include Halana, Kessig Ranger and Alena, Kessig Trapper, two women from Innistrad that have previously been mentioned in the flavor text of 12 cards and now get their very own cards

Keep in mind some of the oldest cards have been around for a couple of decades and the white-back is not a sparkly, brilliant, white anymore
