Boros Heroic is a deck that once was an absolute killing machine in the days of Lurrus, of the Dream-Den that now sits comfortably as a deck that can punish slower decks without removal and can leverage the power of Reckless Rage and Dreadhorde Arcanist to attack fellow creature decks. While not the best option for aggro decks in the format, you can easily transform this reasonable deck into a budget option without sacrificing much outside of the mana-base.
The maindeck is missing four Sacred Foundry and two Inspiring Vantage, which will hurt your turn one to three consistency, but if you are able to acquire those six lands, you have a fully powered maindeck. From the sideboard, there is only one change of Chandra, Torch of Defiance for an extra Redcap Melee. Expensive sideboard Planeswalkers are a reasonable thing to splurge on, but I decided to trade the Chandra for an Inspiring Vantage, since that will affect more games than Chandra will.
This is a great deck for taking advantage of ramp and midrange decks that don’t have as much removal in their maindeck and is one of the highest ceiling decks in terms of how well this deck can do at FNM, especially when you do reasonably in the matchup lottery.
