Hearthpwn

After about an hour of trying, I finally got innervate, Alarm-o-Bot and Ironbark in my starting hand. Started the game and top decked my second Alarm-o-Bot. After Bot #1 tagged his buddy into the battlefield I shut off the computer and cried.

Deck takes way too much luck, I recommend that you don't waste your time.

ITs a very circunstancial deck, Is not even a little easy, its just luck

What about this deck is 100%?  Is it that after 40 games 100% of the time I have not gotten innervate + alarm-o-bot in my opening hand?  If that's what you meant then yes, I completely agree that this has been 100% accurate for me.  Thanks for the deck that soooooo many people seem to get on the 1st try.  Who are these lucky people that get exactly what they need on the first try with the miniscule probability?!?

EDIT:  Finally beat him on try 43!!!  Sorry but given my earlier statement this deck is no longer 100% as I have now beaten him.

Great insight, instead of giving the fish, teach the fishing itself! Way to go!

I would like to add and maybe can be added to the title of deck, but this works amazing against Heroic Lord Victor Nefarious as well as this boss Screen below..

Sorry, but after trying several times I have to believe that the people who were nearly instantly successful with this deck were just super lucky.  Even with a perfect draw, I've had my alarm bot swiped (or double swiped) or killed by flame strike too many times to believe this deck is any better than a 1 in 20 shot to win after a 1 in 10 shot to get the hand you need to even try.

Moving on but thanks for the try.

its 4/30 chance to get those cards and u need them both together to win

I've been trying this deck all day with no luck. The worst is when you have the combo and you draw another bot. Seems like every time you have both in hand all they do is swap for each other. I haven't made it past the 5 round without getting overrun.

Took me little over an hour, but I finally did it. Fucking bullshit fight

This deck is trash. You instantly get out-tempo'd with no way out unless you have alarmo-bot and innervate and a big ass minion on turn 1 which is hard to get.

This one was tough. Only way I won was drawing into 2x Alarm-o-bots and naturalize. I used naturalize on his dragonkin and began the alarm bot combo turn 3, discard spell brood card turn 4, discard brood minion card turn 5, double alarm bot turn 6

Thanks. I am very lucky I manage to do it in first try. 

Turn 1 : Innervate + Alarm

Turn 2 : Sylvanas .. Innervate + Alarm

Turn 3 : KT .. Sylvanas dies, stole his dragonkin .. + Alarm

Turn 4 : Giant .. Clear all his minions then go face. Use his brood spell.

Turn 5 : Same as Turn 4.

Turn 6 : Healing Touch + Use his brood spell.

Turn 7 : ..

Turn 8 : Win

i made an account specifically just to comment on this build.  how much herb are you smoking to sit here long enough to wait for a "perfect draw".  dude.  smfh.  

The deck is the worst. 1st of all. it take 15 min to Mulligan for Innervate + Alarm-o-bot. Then it doesn't matter cause he still has million of Face minions and till you stack really u can't deal with them  . but when u stack its too late.  -10000

Thanks, this worked for me, took a couple of tries but I did it. Chromaggus was the last boss I needed to defeat and imo one of the most frustrating in all of the heroic bosses. The Chromatic Dragonkin is super annoying since he gets real buff if you use your spells. I added Poison Seeds for when he gets too many big minions on board and also 2 Druid of the Saber as you can use the charge to kill the Dragon Fairies or the stealth option to kill the Chromatic Dragonkin if needed. A Swipe or 2 for when he summons Onyxia near the end.

Since there was a lot of rumble in the comments about how shitty or not shitty the probablility of getting the combo is, here is the solution (no advanced math required, no estimates done):

While for a rough estimate 25% is ok'ish, if you go it through (maybe even step by step, drawing diagrams, like you probably learned in school) you have a 10.9% chance to draw a 2 card combo in this scenario (no coin - player, combo has to hit 1st turn).

This leads to roughly 10 Games to get the combo once.

NON ESSENTIAL INFORMATION:

If you wan't you can use cumulated binominal distribution for an estimate (as MdK8) suggested - but NOT as the final value, since you don't draw 7 times, but rather depending on your first draw and keep, 1 2 or 3 times, with each more seperate draws. If you look in said table you'll finde something between 0.8503 and 0.9962, depending on your chosen number (since there are few tables with 1/15th on it). But since you get 1-P your estimated probablility should be between 14.97% and 0.38% (I don't know how MdK8 found 25% in that spot). But all of this is not necessary (and unprecize!), because you can easily draw a big tree of probablilities, multiply and add them together, just like in 6th-10th grade (depending on your school and country^^). This will probably be faster than playing 100 games just to test a theory ;).

Here is a link to a fully done diagram, as "proof" (if you want to call it that) The total numbers are in the top right: https://docs.google.com/spreadsheets/d/1-fkJTP2wsnQ5U74yQ_E-HJQ9frQvRFxfz6I0lNqklxQ/edit?usp=sharing

Hi : )

I re-evaluated my calculation based on what you said. The binomial distribution approach models drawing a card seven times and chucking it back into the deck if you don't like it. Turns out your chances of success are much higher in that scenario. I recalculated the probability using hypergeometric distributions (see my updated original post) and ended up at 8.14%, not taking into account drawing combo pieces twice. Including that scenario would have increased the value slightly, because drawing a combo piece twice does no harm.

Your reply made me look a bit closer and I found an error in my previous "calculations" (The chance of drawing the first combo part is 4/x not 2/x), which lead me to 10,9% or 10 trys to get the combo.

I believe you may have forgotten the chance of drawing P2 of of the combo, when you draw the first card on the first turn. This would explain the 2% (absolute) difference in our numbers. This should add something like [(2 choose 1)*(27 chose 0)/(27 choose 1)]*[1-P( 1 card drawn before)] It has been AGES since I did this properly the last time, so be gentle^^

I considered the first draw as part of the second set of cards drawn through the mulligan, because after you get dealt your second batch of cards nothing is returned to the deck before you get dealt the card in the first turn. It is part of the calculation. Let me explain that part of my post:

P(draw 1 card before mulligan)*P(draw 1 card after mulligan)
= ((2 choose 1)(2 choose 0)(26 choose 2)/(30 choose 3))*((2 choose 1)(2 choose 0)(26 choose 2)/(30 choose 3))

So the first probability is given by ((2 choose 1)(2 choose 0)(26 choose 2)/(30 choose 3)), because you have to draw exactly one of a combo piece, exactly zero of the other combo piece, and exactly two other cards. Now once that event has occured you are going to keep the one combo piece in hand. That means you are tossing away the two other cards during the mulligan. Now you are dealt two new cards and get the one card at the start of your first turn. This is essentially equivalent to just drawing three more cards at once. Hence the second probability is given by ((2 choose 1)(2 choose 0)(26 choose 2)/(30 choose 3)), because you are repeating the scenario from before. Actually I made a slight mistake here, as I forgot that the first drawn combo piece is now out of the deck. It really should be (1 choose 0)(2 choose 1)(26 choose 2)/(29 choose 3). This only makes a small difference of 0.3% for the final probability though. I still arrive at 8.5% roughly.

I think the remaining disparity is due to me not taking into account drawing combo pieces twice.

Works as advertised, restarted 4 times until I got Alarm-o-Bot and Innervate in my opening hand, then started tearing him a new arsehole to match his second head... until he played Flamestrike on turn 4 due to a reduction card and wiped my Alarm-o-Bot. So watch out for that. Restarted again and got the pieces on that same restart, won after 20 turns with Chromaggus already in Fatigue. This is absolutely the deck to use.
