What i am wondering is why wouldn't you use
Nomad Outpost for your lands that come into play tapped like the
Boros Guildgate. This way you cover all 3 colours with a land that does the same anyway. It reduces your risk at not hitting black mana at no drawbacks, it is a
pure upgrade and a cheap card if anything. Other than that, I reckon this deck can ditch the
Boros Battleshaper for
Gnarled scarhide, this deck is aggressive and you aim to win before you can even drop the battleshaper. Lastly I am wondering why this deck does not run
Crackling Doom, it is a mardu coloured deck and it would just wreck face.
Other than that still a nice deck tho, it is a nice few tweaks i could make to my exisiting minotaur deck.
