We've had the printing of Reckless Bushwhacker, so your best threat can be played as eight copies. This is a deck that is almost entirely dependent on the quality of its opening hand and first few draw steps, so redundancy is the best way to gain consistency. I say "almost" because Bomat Courier actually gives the deck some card draw that it was previously lacking, tacked onto a cheap, aggressive, artifact creature which is perfect for this deck.

But the primary innovation with this deck is the white splash. It's made possible by the printing of Inspiring Vantage, which is very close to Plateau in a deck that will almost never want a fourth land drop, much less depend on it being untapped. The white splash then allows a significant power jump with Toolcraft Exemplar and Kytheon, Hero of Akros added to the creature suite.

Toolcraft Exemplar is close to Wild Nacatl here, so no further explanation is necessary. Kytheon, Hero of Akros may seem strange, at first but it's incredibly easy to transform in this deck. A turn 1 Kytheon followed by Ornithopter or Memnite and any Bushwhacker will transform it on turn 2. You can also combine it with either Bushwhacker to transform it with no prior warning for your opponent.

Gideon, Battle-Forged is the kind of standalone threat that this deck was previously lacking. Now cheap sweepers miss your most powerful threat, as do most spot removal spells outside of Abrupt Decay. Its abilities let you contend with larger creatures in combat rather than hope to go wide enough to race.

That added bit of flexibility is exactly what this deck needed. I just hope I don't get any flashbacks.
