Hearthpwn

Hard to say, all 3 have some merit but deck is in such a bad spot curve wise that whatever we choose isn't likely to make a big impact.  This deck is going to get outtempo'd probably every game.  Temple enforcer won't have anyone to buff, cleric might not have someone to heal until around turn~6-8 when you're almost dead.  Shadow word death is normally the most value pick, but still need to fill in glaring weaknesses in curve, card draw, and weak minions in the last few picks.

It's not spiteful smith, but it could be dire wolf, you really don't have many 2 drops, and are really going to need the axe to stick guys on the board anyway.  still hard to pass up dark iron dwarf.  this really is closer than it looks.  if we have to armor up turn 2 its probably over.

Got to 12-2 with this shaman, pretty stacked deck though lol

315 gold, 20 dust, 1 pack, golden unleash the hounds....again. lol +400 dust.

2nd 12 win arena run, 12-1 this time.

Mage:

Not shown, 1 Argent Commander, 1 Lord of the Arena, 2 Flamestrike.

12-2 Paladin

74%.  Don't think I ever went 0-3. 2-3 happened at least twice though.  that's what I get for trying hunter!

anything below 7 is disappointing :[

Some of the replies seem ridiculous.  If there's an issue, it's with the reward system, not the people trying to get they want from Arena.

Did you change your post? I can't see the draft options, only the picks.  The hearthhead draft simulator seems to be much more representative of an actual draft - the hearthpwn simulator doesn't give as many class specific cards as the game does.

Pick 1: Picking Blessed Champion on pick #1 is really optimistic, it usually just closes out a game by setting up a big guy with some ridiculous damage.  It's a dead card in hand often though until then.  I'd pick Mind Control Tech to have a 3/3 for 3, but this is arguable

Pick 3: Venture Co >>>>> Windfury Harpy.  Windfury seems to be overrated, although it could be a cute combo with Blessed Champion.  Doesn't usually live though.  Venture Co is cheaper, and overally usually better value.

Pick 8: I probably pick Smith over War Golem, even weaponless.  Especially if I picked the Venture Co earlier, I'd rather have that than 7 cost War Golem.

Pick 10: I'd pick Young Priestess.  Really don't like Holy Wrath, even though it might be decent because the curve is high.  Just hard to use something so expensive and unreliable.

Pick 12: I have a hard time bringing myself to pick Raid Leader, he's just so squishy and subpar.  I'd go with Archmage, but he's not great.

Pick 13: Venture Co, and it's not close

Pick 14: Razorfen Hunter.  Looking for 2s and 3s at this point.

Pick 15: Wild Pyromancer.  Decent 2 drop, as long as we're careful with spell usage.  Alarm-o-bot is just a do nothing, and will just die before bringing in our big guys anyway.

Pick 16: Worgen Infiltrator is my pick.  Acolyte of Pain being my second choice.  Not a fan of the rifleman.

Pick 20: Would go with Equality over Abomination.  the abomination counter-synergizes a bit, and Equality has extra synergy with hero power + consecration.

Pick 22: Tiger over Mogushan Warden.  I pretty much have the warden as one of the worst 4s, although occasionally people get stuck on him for a turn.  We don't even have a shattered sun cleric, defender of argus, or blessing of kings to buff him.

Pick 24: We need 2 drops, so Mad Bomber here.  Holy Light is pretty much a dead card.

Pick 26: Need 3s, and Acolyte of pain again is kind of sux here, but I'd take him over frostwolf.  I think we're good on big guys , with 2 venture co, tiger, etc.

Pick 27: Wolfrider.  Eye for an eye is just a dead card

Pick 28: Stormwind Champion.  Too much synergy to not choose, this guy is awesome.

Pick 29: You chose a 2/3 without an ability over a 2/3 with an ability.  A damn good ability.  Bloodsail will be a 6/3 or 3/3 enough to be really awesome.  The choice here completely confuses me.

Deck is fairly solid, although a bit high curve.

Watched some of that part, it looks like the draft was really bad.  We've got dead cards like Mind Blast, Circle of Healing, Tauren Warrior.  It doesn't matter how we play it out, it's not going to go well.  I'm not sure about 2 Holy Smites either, have to wonder what they were chosen over.

So, I'm noticing that the simulator gives a significantly lower amount of class-specific cards than tends to appear in the actual arena drafts.  If I was going by the simulator, Mage would hardly ever have Flamestrike, let alone spells o_O

I'm not sure where they got the %s for the card combinations, and don't really know what they actually are, but I thought I'd bring this up.  It makes the simulator a lot less useful than it should be.

Would recommend giving vivafringe's thread on the Blizzard forums a look: http://us.battle.net/hearthstone/en/forum/topic/10261856562?page=1

As mentioned above, you do tend to want cards that stand well alone.  After the first several picks, sometimes you can see cards that will synergize well together, then further picks will mesh together a bit.  This is a huge problem for Hunters, which seem pretty bad in arena.  Going for beast synergy may not even be worthwhile at all.  I'm not really big on arcane explosion anyway, but without Mana Wyrm or a Geomancer it's really pretty mehhhh.

I'd still probably take something like Upgrade on pick #1 though, since weapons are more common, and it has a somewhat usable standalone function, and there are several picks it'll get extra value with - Axe, Weaponsmith, Reaper, another Upgrade, Gorehowl kinda.

I would roll with Molten Giant.  If you have Hexes already in your deck, I'd roll with Molten Giant even harder.

Edit: Other cards that would make me pick Molten Giant more, Stormforged Axe, Doomhammer.  Facetanking + making giant cheaper, yeahhhhh.
