This deck is amazing

I'm having tons of fun with this deck, I suggest to try it before Carpet get nurfed lol

Violet haze over Lab Recruiter? I see that haze fits but maybe ? And double champ is propably a 5 mana card too much but in generall this looks good.

This deck seems a little all over the place here.
What is the purpose of Former Champ in the deck?

Pogo Hopper will be much better with the Carpet after the buffs.
Why Violet Haze? You don't appear to have any other Deathrattle syneries for this card to be much use. 

You have a pretty low curve and tempo-based, so the likelihood of getting much joy from the giants is probably fairly low. You'd need a full hand (which is possible later with the Shark and Miscreants, etc, but by then the giant loses it's impact. Look at what other battlecry cards you could consider perhaps?

Some better options for bouncing the Pogo would probabyl help you here. Something like Brewmaster or the 3/2 chap who bounces minions back (I forget the name).
Maybe even a Vanish or two would help here as well.

Violet Haze is a card generator, I like the idea of getting 2 minions for 2 mana. Mountain Giant can be played on turn 4, if you get the perfect curve... Also there are many other card generators, as Ravencaller, EVIL Miscreant, EVIL Cable Rat, Barista Lynchen and Tak Nozwhisker.

Former Champ is usually very good in many situations when you play tempo Spirit of the Shark. Or, you can profit by evolving the 1/1 into a 6 or 7 mana drop with the Witchy Lackey.

Don't forget that you have access to Shadowstep, so you can do a lot of bizarre plays with the cards that I mentioned...
Anyway, you'll generate a lot of 1-drops to slam with the Magic Carpet :))

@Scorpyon I tried many Pogo archetypes... For exaple: Vanish, Lab Recruiter, and control package seems very slow to me. Perhaps they are true AAA cards, but in my opinion they just doesn't fit in this meta. 
Bouncing pogo looks like a tempo loss to me, also shuffling them in the deck isn't always the best choice in a lot of matchups.

That's why I made this deck. Where Pogo is just a good alternative in the late game instead of your main strategy.
Togwaggle's Scheme is a very versatile card indeed, you can play it on Pogo-Hopper, Mountain Giant, Heistbaron Togwaggle or even Zilliax, and is even stronger after the Myra's Unstable Element plus the [Hearthstone Card (tak nozwhiasker) Not Found]'s effort.

There are very few cards that would fit in this kind of "Zoo" list. I'm testing some other valuable battlecry option as Arena Fanatic, Novice Engineer and Frostwolf Warlord.

You said that "getting much joy from the giants is probably fairly low", I suggest you to try this list before... but be careful to not overdraw lol

lul sorry dude, but this deck is neither fun, nor good

All good. I'll give it a try for a true test of it's experience. My feedback was based purely on looking at the list in a vacuum and how it looks to synergise. I get the synergy between the Fanatic and the Shark - though I'm not convinced... yet. :-)

I'll try it for a while and let you know if I have any further feedback. :-D

As promised, I've given it a good run for the last hour or so and here's what I've found.
A small caveat: I don't have [Hearthstone Card (Taz Nozwhisker) Not Found] so I replaced him with a Blink Fox for my run. But since I never really got a chance to play the scheme more than once in the entire run, I don't think this had a negative effect on my outcomes.

In all, I think the deck runs fairly well - in the same vein as other Tempo Rogue decks. I had a pretty good win rate with it, but my results may be a little skewed due to the overwhelming number of Mages I seemed to come up against this afternoon (Seriously, it was like 80-90%! lol)

The Strengths...

If the deck can start snowballing, it's very strong. Against decks with little or no AoE, I can see this working well (decks like Warrior, etc may give it more problems).
The Shark is super strong, especially with Edwin. I won 2 games with an 18/18 and a 24/24 Edwin in play. Always satisfying.
Shark with the Former Champ is great when you pull it off.

I didn't get to play / see Heistbaron Togwaggle more than once or twice, but he's a lot of fun to play. 

You're right, you can drop a giant on turn 4 and it's good. (Though there feels like a bit of a loss of tempo to do so)

And then... the Weaknesses

The Shark is basically the lynchpin of this deck. If you don't see it, chances are you will dtruggle. 
I don't think the Pogo Hoppers ever got a chance to be played even when they were in my hand for the most part. They seemed to be an awkward addition. If I ever got to the point where I could try and p[lay one, I'd pretty much already won anyway and they were never going to save me in a game.

If you struggle in the early game to find suitable drops (and in particular against aggro - Carpetlock destroyed me pretty soundly), it's simply game over. No life gain or protection and it feels like a Face-Race that you're set to lose.

Lastly, it continually felt like there was a gap in the 3 mana stage of the game. I was often a little stuck for a useful play at that point, and the Rat + Lackey is pretty weak, especially if the opponent is pressing the board. 

Final Thoughts...

I like the deck, it's fun to play and provides some interesting games to enjoy. I don't think it's by any means the strongest Shark-based deck out there at the moment, but I also don't think that matters and in any case, it does have some potential, especially with the buffs on the way which might make things more interesing. Having the Pogo Hoppers with rush would certainly give them a bit more of a solid reason to be in here. 

P.S. ...

Unsung hero of this deck probably goes to Ravencaller. With the synergy from both the Shark and then the Magic Carpet, this actualyl won me a good few games when I needed some big board wipes.
