This deck is such a joy to play, able to create hilarious boards during mid game. It's quite vulnerable to Aggro though and vs. Big Priest, well... the Priest has so many ways to get rid of your board. I got wrecked at least two times by consecutive Psychic Scream, then there's Mass Hysteria, Lightbomb and various single target removal. Winnable of course, but I don't think we're heavily favored in this match-up.

I don't own Sneed's Old Shredder so I replaced it with Mechanical Whelp. Sure, that reduces the number of 8-drops but due to Togwaggle's Scheme (which is a great idea, thumbs up!) this isn't too much of an issue. What do you think about Roll the Bones instead of Sprint? At worst you pay 2 mana to cycle a card but I had several games where it drew up to four cards!

replacement for Kel'Thuzad?

 Some other 8 drop. You want to keep the number of 8 drops in this deck, so the Silver Vanguard deathrattle is consistent. I would go for Charged Devilsaur or Deranged Doctor.

but is it super important or nah?

btw thanks :D

Not super important, you can play it without it.

replacement for Kel'Thuzad?

Turn 4 Deathwing.

This deck should be illegal.

What is the reason in not including Y'Shaarj?

Thinking the same while I was scrolling down to write bro :) Thanks for the effort.

What could be a good replacement for Sylvanas Windrunner?? slowly getting the dust, but for now??

I would personally run Mechanical Whelp: it's cheap and works perfectly in this deck!

of course! why didnt think of it?

 on the other hand, i was facing a lot of aggro, so im considering Safeguard

Sludge Belcher 

Personaly i run Baron Rivendare in this deck.. it works wonders and brought me to rank 5 where i am currently

What do you replace for the Baron Rivendare?

I think a necrium vial as I’m pretty sure the effect with Baron Rivendare doesn’t stack. It’s one mana cheaper and worse in some ways but provides a body. Then again, people run weapon removal and there’s really no weapon buffs/synergy in the deck; so if you’re facing less aggro maybe that’s a better swap. 

My last guess would be umbra; same mana cost but the effects are a lot better if you can keep her up sometimes. 

 really any of these work I think. Personally I’m going to try swapping him out for a Vial first.

Probably Spiritsinger Umbra. Baron Rivendare has the same cost, similar effect and even though it's a bit worse it should do the trick: i use it too as a replacement in this deck

Replacing Umbra is the worst thing you can do with this deck

Well i'm not going to craft it only for this deck in wild. I also didn't suggest not to use it, i simply do not own that card and i'm forced to use other replacement that's it.

Yeah, I understand you, but I couldn't know it - replacing her because you don't have a card and replacing because of reasons are 2 different things. Combos with Umbra and Kobold Illusionist are just worth of using it.
