I subbed out a few things because I had a couple useful epics, but this is a really great basis for a Mech Rogue deck--nice work. I've won 5 straight.

Conceal [/card]is a great combo with Sensei and of course Oil and [card]Blade Fury can be deadly.  You are right that it doesn't have a ton of draw, but Jeeveshelps with that, and the Rogue weapon power gives flexible damage ability that can easily buffed. So the lack of strong draw hasn't been an issue. I really like to see low-cost decks that actually work, and this is one : )

For me, Backstab [/card]and [card]Cold Blood, while useful cards, don't really fit this deck. I also think that 2 Tinkertown Technicians is too much, so I dropped one (it's a little too mid-game situational for a deck that has a strong aggro style). I added an Ironbeak Owl [/card](because Taunts can really halt this deck) and a [card]Cogmaster's Wrench (a natural fit and I had pulled one a while ago but never put it to use--it's really effective here).

Thanks for posting this!

PS: why are my card links not working in some cases?

I agree with all of your picks except maybe #11, Boulderfist Ogre over Mad Bomber. I know you'd already passed up an Ogre once, but I have just found Bombers to be better value in Arena. And big drops don't seem to be a key for Mages because of their big spells, both for direct damage and for removal.

You've got a great set of spells for this one--3 Flamestrikes is enormous. And Flamecannon has become a seriously great Mage card at this point, in Arena and regular play. 67 is very high as well. I think you'll fare better with this one than the Rogue.

Does anyone know a way to change what kind of pack you receive as a reward? I keep getting GvG and would like to get Classic for a while.

I'm a barely adequate Arena player myself, but I like the idea of this thread a lot and will try to participate now that I know about it : )Your first pick was fortuitous in one way (Legendaries!) but a tough one. I like Sneed best too, though, especially as an early pick.

Pick4: Sprint [/card]is hard to pass up. I think I'd have gone for that one over [card]Mechwarper (and I love picking a lot of low-cost minions in Arena too). Sprint is one of the real differentiating cards for Rogue IMO. It can win games; Mechwarpernot so much. At least you got one in one of your late picks. In Arena, where you rarely go through all your cards, Sprint doesn't have the same downside it might have in regular play.

Pick9: This one is just dismal : (  I think you made the best of a bad one, but that sort of spread is what really irks me about Arena. I always seem to end up with a few cards in the deck that I never want to see yet are always in my opening hand.

Pick15: I don't know why the Blade is rated so low. This should be a useful card in this deck.

Pick17 and 22: Conversely, I don't know why Zombie Chow is rated so high.

Pick29: The only one where you went against recommendation. I might have kept the Assassinate. I know you already had one, but it's a great card, and I don't think there are enough spells in the deck to merit a buff minion (unless it was an Azure Drake perhaps). 3 Backstabs is the reason, I'm guessing. I can sort of see that. That's a hard call. Assassinate is a removal card. Backstabis a damage card. But they cost nothing and you have 3 in the deck. It should be interesting to see how that plays for you, actually. 3 buffed Backstabs could help remove major cards late game, but you'd need more draw power in the deck to have a good chance of getting all that in your hand at once. Very hard call here.

Overall, I think your picks are really good, honestly. My comments are super-picky, and you had some hard choices early. I think the deck will be interesting to play, as you have a lot of removal and not as many minions as I would generally want myself, and, as you noted, the curve is weird looking. If you can get through the first 4 or so turns without taking a lot of face damage, you've got great stuff in the higher drops. Your higher cost minions are really better quality than your lower cost ones. Your spells should help to keep the board clear as long as you're aggressive about using them and/or using the hero power to finish removing minions as needed.

My current run is here: http://www.heartharena.com/arena-run/24lp2r if you're curious : )

Wild Growth is just so good when you get it early. It does take 2-mana to cycle late game, true, but the fact it replaces itself means it's not a dead card, just sub-par (and if you're hands running low you probably have the mana to spare).

The thing with Spider Tank (excluding mech decks), Chillwind Yeti, and Boulderfist Ogre is that they're all good but not great. If you have a limited collection they're some of the best cards worth including because they're much better than many of the other base cards and overall they can get quite the value. But compared to other cards there's nothing "broken" about them. Shade of Naxxramas is simply better than Spider Tank since it only takes a couple turns to be better in stats and druid decks aren't in a rush (and the stealth allows it to combo very well with Savage Roar). Boulderfist Ogre doesn't demand to be dealt with like Sylvanas Windrunner or Emperor Thaurissan. Piloted Shredder tends to be considered better than Chillwind Yeti because it's "stickier". If you send a Yeti in to die against a minion with 5-attack (Goblin Blastmage, Harrison Jones, Blackwing Corruptor etc.) it dies and that's it. But if shredder dies you still have something on the field, and that 2 or 3 damage can come in handy. The difference isn't huge, but generally it's why you don't see yeti in high-level play.

If you have the first 3 wings you should also put in Haunted Creeper, Sludge Belcher and Loatheb. Eventually you'll probably also want to include Zombie Chow and Shade of Naxxramas though there's nothing wrong prioritizing packs over wings.

Druid is often largely defined in competitive play by Innervate and Wild Growth.

The two cards have a somewhat different purpose and effect though they work with similar cards.

Wild Growth trades 1 card and an early turn for more advanced play every turn thereafter. Generally if you really want to play Growth you want a deck of minions about 1 mana more than another deck would play on curve. You get all your key cards one turn earlier than your opponent and leverage the value of those cards to get favorable play or tempo over your opponent. This is what is called "Ramp."

Innervate is similar but really only gives you an advantage for 1 turn at the cost of a card but not a card play since it costs nothing. It lets you jump the gun on turn 1-3 with something bigger than your opponent can field. Ideally that gives you trade advantages or tempo which is worth the otherwise dead card. It also fits well in a deck that doesn't have much on the low end of the mana curve since you spend the turn you would have played a cheap critter with an expensive one instead.

Your deck has lots of cheap critters and then a ramp of more expensive ones. That doesn't really fit well into the "Ramp" strategy that these two cards support. It especially doesn't do much with Growth. It could work with Innervate because you could make multiple plays on an early turn which can still give you tempo on an opponent.  (Tempo meaning you do "more" than an opponent on a given turn putting them on the defensive). For this type of deck you definitely want some card draw and Ancient of Lore is generally buch better than Nourish for that. Nourish is in the middle of your mana curve so you loose tempo playing it. AoL is at the top of your curve and provides a body on the board so it maintains tempo while drawing you up.

Typical decks should have 6-8 cards you want in your opening hand which pretty well ensures with mulligains you will have something to start the game with beyond hero power. If you play Innervate and Growth, all your other cards should be 4+ on the mana curve, or a strong 3 play.

Typical ramp usually wants a pattern like this...

Turn 1: 1 drop trade critter or nothing
Turn 2: Innervate
Turn 3: Play a 4-6 drop
Turn 4: Play a 5-7 drop
Turn 5: Work towards combo...
