Before anyone start checking the deck, i have a disclaimer that this deck is a modification of Naill deck, here is the link for the original deck 
https://outof.cards/hearthstone/decks/2086-legend-74-win-rate-tess-rogue

Now, i have a few notes about this deck: 

1- It doesn't use Preparation (same as the original) , most players disenchanted this card after nerf and dont wanna craft it back so soon.

2- This one is a bit cheaper (-3 legendary cards, +2 epic)

3- Reason i made this deck is to counter the cancerous (Rise of the Mechs) that bliz introduced, u find plenty of mechs in Hunters, druids, paladins, even Damaged Stegotron in resurrect priest, plus Zilliax is used in each and every deck for synergy or no reason at all but value !! so came the idea of adding E.M.P. Operative to counter and Lifedrinker to regenerate.
P.S I forgot all about Pogo-Hopper Rogue, so far didn't loose a game vs. them, most of them take a moment of silence after EMP kill the Pogo-Zilliax magnetic combo

4- Tess Greymane removed caz it doesn't have enough value most of the time and Barista Lynchen removed caz most of the time the hand is crowded and its kinda slow
5- Bloodmage Thalnos uses is very limited to fan of knifes vs druid and adds a very little value in my opinion (add it back if u think u need it)

I didn't add a proof caz i didn't reach the final form of this deck, but the original from Naill hit legend
Since the original didnt include guide and mulligan, gimme +10 up-votes and i will add mulligan guide, +50 and i will write a full guide the deck
