Well Cucho your deck does seem like an exceptionally good version of the Boros deck. 2x Pegasus Courser is a huge deal to be able to keep attacking. But Courser is a high pick for all decks - what if you start drafting R/W and then don't get any Coursers? For that matter, what if you start drafting Trumpet Blast and Inspired Charge and don't get passed any Goblin Instigators?
Re Ben Stark's video, well I'd not have picked the Instigator P1P4 - probably would've taken Giant Spider instead. P1P6 I'd take the Neonate, and with that I'm in a deck other than Boros aggro.
What deeply saddens me is how bad Green is. It's not unplayable, but you need to get hooked up in basically every archetype you're playing as the average green deck lacks power. The commons are solid (Colossal Dreadmaw, Rabid Bite, Druid of the Cowl), but rather unexciting and in general you have less redundancy than you'd like; it doesn't help that vanilla creatures are rather bad this format due to how clogged up the ground is.
Heh, and I find green a good colour, perhaps the best main colour even. I'd hardly call the deck lacking power since you have plenty of good commons - Colossal Dreadmaw for example is great, but you also have Bristling Boar, Rhox Oracle, even Thornhide Wolves is quite good. You have plenty of redundancy because your common creature base is so strong. I disagree that vanilla creatures are bad - because of how clogged up the ground is, what matters is having bigger creatures than the opponent. I don't mind playing Thornhide Wolves for this reason, and I find Colossal Dreadmaw, Ghastbark Twins, etc strong cards. Only weakness with green is that you're rather short on removal, but the second color can compensate for it.
