Ghitu firebreathing was indeed trash. At the time I picked it I wasn't as heavily in white as I ended up being at the end of the draft, and I really should have cut it.
The spirit loop was also frequently boarded out, although the plan was for it to be put on evasive creautures to help me win races.
I don't think grapeshot would have been all that great because early game you are playing out all of your cheap cards and then generally late game playing bigger things. It's pretty contitional and I don't think I would see it storming for more than 2 very frequently.
Cutting Urza's Factory would have been the right call also, as well as the Restore Balance, since they were both pretty much useless.
I don't know if the Channeler is as good as you think. Their x/1s can be taken care of by Zealots and other than that I just see it tapping+discarding pumping a 2/2 to trade with a 3/3, when I could have just double blocked the the 2 2/2s anyways. I don't think it's that relevent when I'm attacking, either, because of the evasion in this deck you can almost certainly win if you stall them long enough to get the job done.
Thick-Skinned Goblin is probably better than I gave it credit for. The Halberdier is good but only against certain deck IMO (although I did board it in alot so maybe I should have had it maindeck and boarded it out against decks hostile to X/1s.
Gustcloak Calvalier was amazing, though. Taps when attacks, if they block to kill him you just untap+remove from combat, and if they don't they take 2 damage. The fact that he has flanking as well makes him even better. This guy is as annoying as hell for your opponent. (although I admit 5 mana is a bit expensive)
I also don't think you guys realize how good the War Marshal is. Most of the time you chump with him and it's basically 1R: get 3 1/1 red Goblin Tokens. That's good. If they don't attack then you either pay the echo and hope to trade him later or you get 2 1/1s for 1R (which is not bad). Them not attacking is also good for this deck.
Also, the Flickering Spirit is really good. Although I did only use the flicker ability a couple of times, 4 for a 2/2 flyer is not bad when I'm paying 3 for 1/1 shadow guys. A 2 power evasive creature adds a lot to your clock, and lategame his ability to attack, flicker, block, or stack damage, flicker, and live, shouldn't be unerestimated.
Oh and the Dragoons I found were just too expensive in a deck that already has a lot of high casting cost creatures. Most of the time by the time I could cast it I just wanted to play something else instead. The should have just reprinted Radient's Dragoons instead; that card is so much better, and their's already echo in the set.
So, in hindsight I probably would have cut the 2 Factories, Firebreathing, Spirit Loop, Restore Balance, 1 War Marshal, 1 Jedit's Dragoons, added 1 Plains and the Thick-Skinned Goblin and Keldon Halberdier. Making the deck 41 cards (since I like the extra "1/2 land" 17 land in a 41 card deck gives; I think it would fit the curve pretty well)
That should have configured your deck a little better for what you faced. Basically, you won because your opponents were either manascrewed or idiots (nice land 5 you got off that Dryad), not because you really had that awesome of a deck.
Oh, I pretty much agree with you. The deck was ok but not really that great. I wouldn't necessarily say that my opponent's were always either mana screwed or idiots (that seems a bit of an exaggeration; I see the first match and the 5th land thing later on as extreme examples or outliers rather than good examples of how the draft went overall), although as always luck and play skill are indeed both determining factors. Some of the games were very close, although I find that that is not necessarily the norm in draft. Often you'll get mana screwed first game, your opponent will get screwed the next, and then it all comes down to game 3(and of course if you get screwed in 2 out of three games there's not much you can do). I feel happy if I can get 1 good game per match, generally, although I'll reiterate that this is just my general impression of things.
