Been trying to find a deck for standard, and this is one of the ones I am working on, though I am not sure if it is strong enough, either is color, theme, or just as it is right now. Now one of the main things that I could think of is the lack of removal, but I would like to get any opinions upon this list:

I'll be honest here, I don't know that the deck has enough power to really get there. The creatures are, on average, small, and all your heroic triggers are protection spells... so you're going to hold them longer than you need to and once you start committing them to work your triggers, then the opponent will have removal. Toss in that Anger of the Gods or Drown in Sorrow will just punish you heavily.

I think if you're looking to go with a Heroic and Outlast build you'll want to shift some things around and potentially include red. Red gives you Akroan Crusader, Anax and Cymede, Dragon Mantle, Titan's Strength, Coordinated Assault, Goblin Rabblemaster, and even small scale burn in Lightning Strike or Stoke the Flames in the event you want that. Toss in added heroic triggers from Warriors' Lesson and you're onto something. This could give you a more aggressive build that, in a pinch, can make everything flying via Abzan Falconer to finish things off. In this route I'd also consider including High Sentinels of Arashin as a 3x finisher (given that most of your stuff will have counters, this is a HUGE flyer). Keep in mind that Ajani, Mentor of Heroes or Ajani Steadfast would work wonders in here too.

Alternately, you could go midrange and make it full blown Abzan Heroic and Outlast (with the stronger emphasis on outlast). You don't really use outlast as much, but you could easily use the outlast boosts to make a pseudo sliver deck. Then you get access to all sorts of things ranging from Anafenza to Siege Rhino to Abzan Charm (this card is a friggin bomb). Toss in most of the outlast enablers as 2-3x, toss in a few ways to put counters on your guys (Reap, the Ajanis, etc), and all of a sudden you get dangerous.

I don't think either one is going to beat a lot of tier 1 decks, but then again, I've seen stranger things.

I would have to agree upon the addition of red. Naya is much more diverse in what it can do, and adds a lot I did not have with my build. But even still the removal does seem to be the major issue with creature-based decks such as this one.

I had never really seen the power of the High Sentinels of Arashin till I put two and two together aboout all of the counters, and for a 4 drop that comes in as a 3/4 flyer, let alone its added "put a +1/+1 counter on target creature". And with Ajani, Mentor of Heroes, I'd say it favors the deck quite well, though I am not as big of a fan of Ajani Steadfast.

Abzan seems quite lethal, even more so with the cards you introduced me to. Abzan Charm I had known of, but I didn't even think of it in the deck, then Siege Rhino, I don't even know how I skipped over that! As a whole, it seems like it could get rather nasty, but its hard to say how removal will tear it apart.

I do not think it will be going well against tier 1, but you never can tell. Looks like my hold upon G/W little kids will have to be let go.
