Here is a deck I constructed. I'm really not sure of its viability in this future meta but I think there's a chance it comes out as popular.

Don't be afraid to give feedback and your thoughts about it. Do you think this will become a new rogue archetype?

p.s. I give more explanation on what I think of the deck directly on the deck's page

I think Mistwraith is very underrated and so are Echo cards. It all greatly boosts the power of Sherzin too so I'm pretty sure this will be good.

I've done a lot of Standard brewing for this set and I've got some pointers very much worth sharing regarding this particular deck:

1.) Not that the deck is bad but it's definitely slow and could be much, much faster. 

VtH is powerful here but has no synergy with Echo whatsoever can be next to dead late if all you have left in your hand is durdly cards; making sure that most of the deck is cheap and flexible just for her sake is extra-important.  Speaking of durdly here, Tess Greymane certainly is on her own as again the deck has a heavy echo theme and alongside that theme you must also play enough of your opponent's cards for her to be a worthwhile play - not every turn in Hearthstone is turn 7+.  Finally the Baleful Bankers are dead draws until you both play an amazing target for them and have mana to spare; also cutting them from the deck can save you a lot of dust as I'm willing to bet that most Standard decks that will really want to run him won't run more than 1 of him anyway.  Replacing any number of these cards with assertive 1/2/3-drops can help speed up the deck immensely and make it more consistent to boot.  Also with enough tempo Obsidian Shard is very worth including here as well, at least as a 1-of.

2.) Countess Ashmore will tutor Sherazin, Corpse Flower!  Add some Rush minions and suddenly this deck has a Curator-esque 7-drop that always hits a really important target and can potentially draw you 2 more cards!  Also worth noting is that if you add Cold Bloods and Vicious Scalehides you have another potential draw from Ashmore and a 3 mana 5/3 rush lifesteal combo which is great for anti-aggro!  

3.) Spell damage can be huge in this deck, perhaps moreso than you might think.  Consider a lategame turn of Cheap Shotting with spell damage!  Also, VtH can dupe spell damage minions for an extremely strong play or can dupe Backstab, Fan of Knives or a spell from an opponent's class with a spell damage minion in play.  Tainted Zealot is the go-to minion for spell damage in Standard right now and will turn a Cheap Shot played twice into a much better Multi-Shot.

4.) I know it's a laughed-at card right now but Lilian Voss will replace your echo spells that you play on the same turn with another random spell from your opponent's class instead of letting them disappear from your hand at end of turn!  At least I'm sure that's how it'll work; I'd be really surprised otherwise.  She'll replace bad burgled cards that you haven't played yet with other random spells as well and therefore makes her a mulligan with with a solid body to boot.  

If you don't want the "play different class cards" part to totally die when encountering a Rogue, you could run one or two Witch's Cauldron, just to get at least some cards to fuel Tessa and the Cutlass a little bit.

Walnut Sprite?

That card is terrible.

Still, a nice list.
