What about Ankle Shanker? http://mythicspoiler.com/ktk/cards/ankleshanker.html

It wasn't in the database when I built this

Too few creatures...

Strive is mostly terrible if you're not running Green.

Stoke the Flames

The mana cost on Zurgo is a bit steep for this build though I've considered but playtesting will prove I've made more changes suggestions appreciated. +1s if deemed worthy.

i would suggest running 24 lands with this build. cut Stoke the Flames put in Wingmate Roc cut Eidolon of Countless Battles put in 3x Brimaz, King of Oreskos cut Hall of Triumph put in Sorin, Solemn Visitor cut 1x Mardu Ascendancy and cut the 3x Suspension Field and put in 4x Banishing Light cut 1x Frenzied Goblin put in 1x Ankle Shanker

this give it plenty of token production and team buffs. with good removal that hits almost everything ;)

Have you given a thought to Ankle Shanker I feel like it would go really well with your horde

Had decided to end the curve at for had em in before then pulled utilitarianism see PLAYTEST will determine. Thank you.

Instead of chief of the shield use athreos god of passage as he makes the creature more resilient. +1 for choosing mardu aggro

Nice deck. +1

Took a few playtests to see it start firing appropriately. For some reason the mana draw seems sketchy. Maybe that's just the computer hating me but I often struggled with my starting hands and drawing into what I needed. Granted it's three colors but if your CMC is going to float closer to the tail end of three mana than you should definitely run closer to 24 mana. Even one more mana can define the difference.

32% of your deck is multicolored. 24.5% of that is a CMC of three or higher. Almost 19% of the deck is CMC 4 or higher. Less than 30% of your deck is land.

I understand this is all information you could see just as easily for yourself, but it really changes the perspective of your deck when you sit down and look at it closely. If you're playing a high cmc aggro you want nothing in the way of preventing your creature drops. Insufficient mana is the most obvious and common way to stunt that. I'd consider tweaking your mana base to better match your card costs and also increase the number of lands by one or two.

Of course I've only toyed with it for 10 or 15 minutes. But that's my first impression. Best of luck! Enjoy your pre-release games!

Would Hammer of Purphoros have a place here?

After playing in the pre-release twice, Raiders' Spoils seems to be pretty good with enough warriors. You seem like you have enough to add at least 1. Think of it this way, you could draw a retarded amount of cards for the win. Not to mention it speeds the clock up and is not multi color. I can see dropping 1 of the mainboard Dictate of Erebos for it.
