Boros's Initiative

Hmmm...so, this deck isn't hopeless. Please take it off Unloved because with some tweaks, this deck could be great. Allow me to help.

First off, sideboard Chained to the Rocks. If you're trying to throw down creatures and pound in some faces, you don't need Chained to the Rocks. You don't need control in a creature-heavy aggro deck, do you? Just something to think about.

Now, I'm not trying to hate on the Reckoner, but do you /really/ need four of them? I would suggest running two, then have some low drops (i.e. Legion Loyalist or Boros Elite) and I could see a splash of Battalion thrown in here, seeing as you have a token generator (Elspeth).

Soldier of the Pantheon is an amazing one-drop, don't get me wrong, but put him on the Side. Let me explain why. Yes, he's a 2/1 for W, but his ability is actually very, VERY situational. If you're facing, say, a mono-black deck, SotP isn't going to help you very much because his ability will have nothing to do with the game. Make sense?

If you have no Flashback, then Ash Zealot won't be of much use. I don't often see a lot of Flashback used. I would throw in Warclamp Mastiff, Boros Elite, Legion Loyalist, or Firefist Striker. Ash Zealot burns only when a spell is cast from the grave. You have no Flashback in this deck and there is not often much flashback in a deck, based on what I see. I could be wrong, but at the very least side Ash Zealot.

I'm trying to find where you have enough targeting to warrant Heroics, but I don't see it. Now, I would replace Anax and Cymede with, perhaps, Tajic, Blade of the Legion (2/2 for {2}{W}{R} - Indestructible AND Battalion +5/+5 for him) or replace your Chained to the Rocks with Coordinated Assaults and Swift Justices if you want to keep your Anax, but cut it down to 2. If you get a hand full of them, you're gonna just be sitting on them due to Legendary rule.

On that note, if you're going to run some more targeting stuff, run Akroan Crusaders. Another fun token generator for just one red mana!

Also, I'd up it to 22-24 land. 21 is fine, but if you start noticing any mana problems with this deck, add more Plains. On that note, why are you running more Mountains than Plains when there are more instances of White requirements than Red? I don't think you noticed that. I would invert the numbers a little.

Now, there are aspects of this deck I really do like. Your inclusion of Boros Charm was very good, but ensure that you use it for either indestructibility or making a creature go BOOM unless you can use it on an opponent to win this turn or you have some lifelink or a double strike would help (with targeting or winning the game that turn). Some may disagree with me on that, but it's totally up to you.

I like Elspeth being in this deck. She is just mean!

I like your potential boardwipe (Mizzium Mortars). That was a very nice touch.

Magma Jet was a very good card to put in, primarily for its Scry 2.

This deck has potential and I think it could go far. Tweak it some, and it'll be fantastic!

One final piece of advice (so you don't ever feel as though you need to Unlove a deck): Think of deckbuilding as putting together a puzzle. How does each piece (or card, in this case) fit with one another to make a sound hole? When you build a deck, look through it. See where certain core effects may not be as widely-used within that deck as you thought it would. See how some cards that look great could be sideboarded because they have situational abilities. Keep this in mind and you'll go far.
