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.
