Hey there. As a Boros guy I build a lot of Boros Stuff. Look at my full list of decks to see everything. but this deck is similar to one of my first decks. Unless you're playing Boros Control, and it doesn't look like you are, the object is to kill your opponent in about 6-7 turns. What you have looks good except for some of the enchantments. Assemble the Legion is a good card in long games, vs control, so I would Sideboard them. With those three spots opened up, I would add 4x Viashino Firstblade and pull 1x Tajic, Blade of the Legion . Tajic is great if you get him going but since he is legendary I wouldn't run more than 2x. Viashino Firstblade is awesome because nobody expects something like that turn 3. And similar to that, Spark Trooper is a great card to just womp someone in the face and gain 6 life at the same time. I might even pull it for Aurelia and Tajic but that would kill you if the game lasted longer than 7 turns. Think about this.

Turn 1: 1x Plains and 1x Boros Elite .

Turn 2: 1x Mountain and 1x Akroan Hoplite . Swing for 1 with Boros Elite . Opponent at 19.

Turn 3: 1x Mountain and 1x Viashino Firstblade . Swing with Boros Elite , Akroan Hoplite , and Viashino Firstblade for a total of 11. Opponent at 8.

Turn 4: 1x Plains and 1x Spark Trooper . Swing with Boros Elite , Akroan Hoplite , Viashino Firstblade , and Spark Trooper for a total of 16 and +6 life for you. Opponent at -8.

I would consider pulling 1x Mountain and 1x Plains and 2x Gift of Immortality for either 4x Legion Loyalist or 4x Soldier of the Pantheon . To be a good aggro deck you need more 1 drops. I would also pull 4x Wojek Halberdiers and add 4x Firefist Striker . The Wojek is good but tapping blockers and getting damage through is more important than killing a blocker.

Sorry for posting that twice. I posted it without being logged in once and then posted again when I did log in.

I would suggest taking out 1x Aurelia, the Warleader , 2x Assemble the Legion put in another Boros Reckoner and 2x Brimaz, King of Oreskos . I think that would help make your deck run a bit smoother by smoothing out your mana curve. plus you could think of running a couple of cards like Boros Charm , Warleader's Helix and Aurelia's Fury
