G/R Aggro decks are typically straightforward. You want the most aggressive creatures with a good curve and you back them up with a smattering of removal spells (preferably burn for some reach) and pump spells.
That's essentially what today's deck is...but the list is anything but straightforward. Starting on Noble Hierarch makes sense, especially when you have a three-drop like Goblin Rabblemaster that benefits from entering the battlefield as soon as possible.
The other one drop, Aether Vial, isn't usually found in this kind of deck, but the curve is condensed enough that it works. It's especially good with Huntmaster of the Fells, which you can vial onto the battlefield and transform on the following upkeep. It also helps you break the symmetry of Eidolon of the Great Revel, one of the deck's best two-drops.
Eidolon of the Great Revel is a bit of a weird choice for a deck that's trying to cast a green one-drop, but the mana in Modern is good enough to make it work. Eidolon's stock has risen a lot recently with the emergence of U/R Gifts Storm, a deck which this list is clearly targeting with not only Eidolon but several ways to interact with graveyards in game 1 and Scab-Clan Berserker.
The numbers here look strange, but every card (with the potential exception of some of the singletons) is a solid rate for an aggressive creature and the curve is good, so while the parts may look weird in a vacuum, their sum is cohesive. There's a lot of ways to deal incidental damage as well as a few ways to go over the top in combat.
Combat Celebrant is the main way to accomplish the latter, but don't overlook the synergy between Smuggler's Copter and Goblin Rabblemaster. The vehicle lets you use your Goblins to crew when your opponent has blockers back ready to eat them, allowing you to amass a large battlefield while your opponent is always forced to play defense. I'd like to see more Smuggler's Copters, but the card is admittedly weak with Aether Vial.
My first impression of this deck was that someone built it out of their trade binder, but even if that's the case, there was some good work that went into it. You could clean up the numbers a bit and come out with an aggro deck ready to compete with the best of them.
