Hearthpwn

4 mana for a respawning 1/1 is difficult to justify I think.  It does make for a good Power Overwhelming target though...

2/2 is a bit underwhelming but the effect is neat and I like the direction Blizz is going here

I'm not implying that you're bad. I understand what it's like to pick up a new deck and have poor results because it used a play style I wasn't familiar with. The reason I know it's you and not the deck is because people have been piloting this deck and it's many variations to legend since... like forever.

You can find players piloting Zoo decks at all ladder ranks. Why do some get stuck at rank 16 while others reach legend?  A little of it has to do with RNG, but most of it is knowing the strengths and weaknesses of your deck and match ups and playing to your strengths. 

Find some high level steamers that are playing Zoo, or watch some YouTube videos. I'm sure you'll pick up some good tips and tricks to use along the way. 

You sound new. Don't take this the wrong way but it's not the deck its you. This post doesn't have a guide attached to it. Find a similar one that does. Most likely you're playing the deck the wrong way. The mulligan, minion placement and knowing your match ups are very important for this deck. Keep playing it and I'm sure you'll have better luck.

Definitely 

Definitely not sold on this card.  I guess time will tell.

I'll wait to see how many more dragons are released.  I think it's too early to call this a good or bad card.

Turn 1 Dragon Egg

Turn 2 Cruel Taskmaster

not a terrible combo ...

This deck really looks like a lot of fun.  I can't wait to try it out!  What is your condition for playing Feign Death?  Do you try to hold on it until you have a couple of the legendaries on board or are you content to use it on some of your early drops (webspinner, mad scientist, loot hoarder, harvest golem)?

Ok, I just hit this deck 5 out of my last 6 games what does well against it?
