I think you need to use the "Share this arena" Link, that one won't connect for me.

Had to click around a bit to find your Arena run, but found it. (I was looking at the Hunter draft.)
Looking at your draft there's a few things I'd comment on:
1) I don't think you value Blackwing Technician highly enough as a card without dragons. It's certainly better than Windfury Harpy (#7) and probably better than Cobra Shot (#9). A 2/4 body for 3 mana is at least an Average card.
2) Having a Zombie Chow in your hand at the start of the game is so valuable that I'd take it over an Ancient Brewmaster (#6), which has a decent body for 4 mana, but I find bouncing a minion back into your hand hurts your board as often as it helps it by using it to recast a battlecry or heal a minion.
3) At the point where you turned down a Force Tank Max in favour of a Faerie Dragon (#16) I think you needed the Force Tank a lot more. You only had one real big drop at that point (Boulderfist Ogre) and you already had several playable 2s. With over half the draft to go you weren't desperate for a 2 right then, but Force Tank is a really good big drop.
4) Shieldbearer sucks (#26), I'd take a Hyena with no Beasts over that card. (Plus you had an Unleash which is at least one card you can combo a Hyena with).
5) I think I like Madder Bomber's ability to turn the game around more than I like the survivability Arcane Nullifier (#27) gives you, but that's at least a close call. Nullifier might have been the correct choice.
6) In your last choice (#30), Bomb Lobber should not be underestimated and fits your deck a lot better than a Deathlord. Bomb Lobbers might have small bodies for 5 mana, but that 4 damage is a big swing and usually lets you get a 2 for 1 off the card. Deathlord usually kills 2 little things, but if it's up against a 4 drop like a yeti it sucks because gives your opponent a card for free. Bomb Lobbers are also more aggressive cards letting you surprise remove a card when you just want to drop some damage whereas I think of a Deathlord as a card that helps you stall the game for the late game (when your deck is better for early-mid game than it is for late game).
