That combo isn't reliable at all though - it relies on you drawing a 1/30 card in your deck along with a 2/30, and then also on you sticking a big minion without it dying, and without your opponent playing a taunt to block it (you have no way to get around taunts either). Windfury can also absolutely be dead if you don't have any creatures that can attack this turn.
Meh, edited it to have two Windfury cards (well before you posted
). So it's 2/30 and 2/30. Which isn't any worse than virtually any other combo, except this one can be applied to more things. It would be better with more card draw, but the wide range of targets compensates for this a little.
Some charge would be nice, but I can only really think of Leeroy as an option in place of the Faceless Manipulator, but the manipulator is useful for so many things I'm not sure what is better. FM goes great with stealing legendaries or becoming a dragon or EE (with no downside), and can be another threat very easily if you've windfuried one already. It'd be very easy to take out the Earth Elementals entirely for either Fire's or whichever 1-6 mana card you particularly like. They're not the weak link, but they're not the strongest either. I just like giving them some play (and the opponent does run out of answers eventually. Then, Kapow!). Likewise, the Shattered Sun Cleric can be dropped for any 1-3 mana card you like (flametongue or more removal?).
In the end, it's normal zoo. Your creatures take down their taunts, you must have creatures on board to be effective, and you can stall out due to this. Your creatures tend to be a bit bigger than normal, which helps against some of these things, but it's still just zoo with a "go" button. Which isn't really ever a terrible thing. Crackle can go to face or creatures, one ES/Hex/BGH is a fair bit to take care of the bigger threats, an axe for the smaller, AoP tend to make board sweeping a bit more annoying for the opponent (and can sometimes do wonderous things against token decks if you end up with a healing totem in place). So yeah, there's bits, and they're fairly good bits, but reliability is a concern.
It's not a "Legend" level deck (although it might be fun to test it up at that level), but it'll certainly get you up to rank 10 or so with enough play. Virtually any zoo deck will. I just happen to like this one better than zoolock or hunter. It feels more strategic, while still being able to give some cheap'n'cheesy wins. You don't have to save back a win combo, you can just use them to pip more damage at creatures or face, but at least there's options with it. A good player could take the deck quite a bit higher than rank 10, quite easily.
Anyway, I like it, and that's the main thing
