INTRODUCTION
Well, it looks like The Lich King isn't the only one who marches on the lands of living and brings death. After a long eternal slumber, upon hearing his plans, the corrupted twin gods are also on their ways to cause destruction and death.
(Update-I: Updated as of Patch 26.2 - Festival of Legends Balance Patch. My E.T.C cards: Togwaggle's Scheme+Potion of Illusion+Spammy Arcanist)

(Twin N'Zoths in action! Taken during MotLK expansion.)

(20 battles with 65% win-rate. Looks like Twin N'Zoths aren't that bad.)
(Taken during MotLK expansion.)
GAMEPLAN
Edwin was hired by twin N'Zoths to bring death to anyone who confronts him. Fortunately, he has a trick or two up his sleeve and completing his mission won't be a big deal...
- Spiritsinger Umbra: Edwin made a deal with Umbra, so that she can summon an everliving army to conquest. A fellow adventurer can check these two pictures down below to grasp as to how. She can also do the following tasks for Edwin:

(Korrak...)

(...is back! Taken during MotLK expansion.)
What matters the most is for twin N'Zoths: If either of them are wounded, they can fall back with Time Rewinder and Bloodthistle Toxin to counterattack later on the battlefield.
- Potionmaster Putricide: As a tactician and experimenter, he likes to form up a wide array of potions from the dead to toss into the battlefield, spreading the death even further. One can look at this picture below to see the brilliance of the Professor...

(Putricide, still brewing potions while settling things with Rexxar nearby a graveyard.)
(Taken during MotLK expansion.)

(How many of twin N'Zoths will come back? Who knows? Taken during MotLK expansion.)
- Flesh Behemoth: This deadly behemoth has an element of surprise by its nature. Let's see how...

(Aftermath of Implock thanks to Flesh Behemoth and Kel'Thuzad. Gul'dan looks very deadly.)
(Taken during MotLK expansion.)
- Sonya Shadowdancer: She is always eager to fight and covers her comrades if they fall. She dances with shadows thanks to her cloak and brings her fallen comrades to first-aid tent, so they can return the battle anytime...

(A kobold was saved from the battlefield! Taken during MotLK expansion.)
CARD SUGGESTIONS
If you've read it so far, that means you really are interested in this guide, and of course, the deck itself. Thanks for reading, I had a very good bang out of preparing this guide and playing it. It's really funny deck to fool around, yet some people might not be able to experience it the same due to lack of cards and/or dust, maybe even preferences. In that case, I'm here to save you from any trouble, so keep reading...
- Xaril, Poisoned Mind: He can help you out in different ways. He grants attack, draws a card, and most importantly returns your N'Zoths. I can relate that spending 1600 dust for multi-tasking can be too much, so why not have Shadowstep? If you have Shadow of Demise, it can be even better when a N'Zoth is on the battlefield and you cast Togwaggle's Scheme twice.
- Zephrys the Great: A staple for Highlander decks but here, I can understand if you don't want a plain 3/2 summoned by N'Zoth, God of the Deep. If you are low on dust, Violet Haze can give you resources. Maybe you can find Mi'da, Pure Light from it, who knows?
- Kel'Thuzad+Baron Rivendare: Both can be crafted for a total of 3200 dust or you can get them by purchasing Naxxramas adventure set. If you can't get them for whatever reason, you can swap with any card. Armor Vendor for defense and Blightnozzle Crawler for poisonous hits can be deadly.
- Sonya Shadowdancer: Her retrieving ability as 1/1 shouldn't be underestimated, which can be used in conjunction with Spiritsinger Umbra. If you can't craft her, Necrium Blade can serve you well to setup a Deathrattle minion for good profit.
- Potionmaster Putricide: Potions are fun to have a blast with. If you don't have him, you can try your luck getting one with Weaponized Piñata.
That's all for this deck. Thanks for reading and have a good day or night, wherever you are. Have fun in Wild format!

Thanks for the compliment, that means a lot. Though my narrative may not be so good, I'm always trying my best to point out the core of whatever deck I make ^_^
