While there were three different color combinations featured, if you chalk them all up as "Human Tribal" the deck made up half the Top 8 of the Baltimore Open. All four decks featured Always Watching. Two splashed blue for Reflector Mage and Dragonlord Ojutai. Another splashed green for Tireless Tracker. Lastly, the second place list kept it to mono-white.
Immediately, the numbers on the one drops look odd, though the explanation is to decrease your odds of losing two creatures to opposing Declaration in Stones. Dragon Hunter is marginally better than Expedition Envoy, and Town Gossipmonger // Incited Rabble is either better or worse than both, though the numbers are simply a hedge. I'm inclined to believe that Consul's Lieutenant is just better than Hanweir Militia Captain // Westvale Cult Leader though, and I'd chalk this one up to experimenting on week one.
One advantage of playing Pastore's list is that your manabase will be more consistent, though the technology that really stands out is Gryff's Boon. Gryff's Boon is reminiscent of Rancor with regard to being a cheap aura that pushes damage through and doesn't always lead to the card disadvantage typically associated with auras. It's not as efficient as Rancor, though granting flying will often be better than granting trample.
There was been a lot of movement in the price of white rares after this weekend, and I can't endorse investing in staples from this deck. The deck is great, and if you want to play it then by all means buy in, though this is a much better time to be cashing in the Declaration in Stones that you pre-ordered if you were so wise as to do so. These prices will be stable and possibly see even more gains going into Pro Tour weekend, though things will settle down after then.
