There are a lot of ways to generate tokens in Boros and a lot of worthwhile creatures to trigger Kalemnes abilities

Reference Or Reality

Breath of Fury I love extra combat spells almost as much as I love weird creature auras so you can imagine how this Ravnica gem is near and dear to my heart

The stats on many of red and blacks cheap common and uncommon creatures are extremely weak, and most combat tricks you have access to will not help them survive a block

Overall, its nice to be able to play the deck as a toolbox deck with answers to many different situations or permanents, so if playing blue/green control strikes your fancy then Momir Vig may be the general for you.
