I'very built a similar deck around assault formation... my only suggestion would be jeskai barricade to bounce siege rhino or spidersilk net for flyers. +1 sir.

Well done sir, you just opened a new can of worms for me... +1
love the deck, solid combo of heroic and prowess. Only suggestion is Triton Tactics as for 1 mana you can trigger 2 heroics and prowess. Phalanx leader double white cost wouldn't fit neatly in your mana curve. Solid +1 deck.
Like where you're heading with this, looks very quick. Only suggestion I could offer is oppressive rays, I find it gets people on the defensive quickly.
Love this deck, I run a slower version with a few more creatures (Battlefield Thaumaturge Infinite Combos) but this is a fearless, no waste, blitz. All for 2 mana or less, an easy +1.
