Again, this doesn't matter so much over the long term because the supply of these decks will be massive, so things will even out, but for the short term, having $30 more in value is a reason to take Stalwart Unity, Breeding Lethality, or Invent Superiority over the other two decks
The reason is because the UW one feels like the default commander and White makes Allies the best for waterbending purposes, but Black offers some really powerful waterbending spells and more Clues for waterbending purposes
Both are legal in tournament play and add flair to any deck or binder
