While I could comment on a lot of the faction choices you made. I think I'll keep my comments to my favourite faction, Flame Dawn.
If your list is indeed based on after choosing commanders I think you've made a few mistakes.
Agent Coyle: If you end up two purity flame dawn you are looking at rushing your opponent down, this makes him one of the best Flame Dawn cards you can take in your deck due to his surprise nature (especially if hiding behind a few other cards to let him sneak in for 21 damage). He can transform late game into a multi strike dragon. Oh and if you have Aberion's banner don't even get me started
Bloodbath: I've never seen someone pull this off in draft successfully, and it's very difficult to pull off in constructed (due to the weak nature of Flame Dawn cards). I would move this down one level under dragon of the summer flame.
Bromich: Part of what makes Flame Dawn really good is the ability to hit hard and fast, while he is a Good card to have in your deck, he is the Best card to have as your commander. He is for sure not the best card to have in your deck at the rare level.
Paladin of the Flame Dawn: Why is this only Good? This card is amazing against Verore, it's insane if you manage to get a buff onto it from GI or DoD. On the rare level I would place this as one of the best cards to have from flame dawn in draft. Does this make it the best card to take? No...but it's better than most rares (except Protector) as a part of your deck.
Mark 1 Brimstone Tank: While this is a nice beefy character, I think that you get more out of Pyr (Constant pressure) and Aberion Banner (Bigger charge creatures). I would probably move this down to the same level as those two for purposes of draft pick.
Purify: I don't think people have picked up on the potential of this in draft yet. I've had two people concede to me after I removed vital parts of their game (Once I purified away all 3 of the deck secluded constructors, the other time I purified away 2 pack leaders). I would put it on the border of the two but I almost think it needs to move into the best category
Call the crusade: This card can be a game changer if played at the right time. Perfect card to avoid Mass Death with, great way to punch through for the win when your opponent thought he had the perfect amount of defenders. I take 2+ of these quite often when I go for a rush deck using Flame Dawn and usually get 20+ wins with about 1/4 of those happening off call.
Note: These are all just opinions but this is based off multiple 20+ win streaks using Flame Dawn
