EldritchSage didn't specify the playstyle for this deck
I think this pairs best with partner commanders that either add card advantage (Tymna the Weaver) or access to colors with ramp (Jeska, Thrice Reborn or Reyhan, Last of the Abzan)
At current box prices, however, singles are the more cost-effective route for specific competitive needs
