Quite and easy concept, ive toyed with deathrattle rogue alot within the last expansion and am excited for the upcoming cards that will change this deck for the better...
the deck looks very late based but with Aknu you can achieve a huuuge board presence by turn 6, don't be afraid to have your units drop off since N'zoth is here, you have 1 of 3 different types
Scrapyard for your elemental, Plagued protodrake for your dragon and i really think it will have its value in this deck the Darkmoon rabbit.
you will be able to reproduce your board over and over, from your first N'zoth you return it to hand with shadow step and next turn play it with togwaggles scheme, if you feel brave and try keep N'Zoth out on board, i'd only suggest doing this if you have Tak Nozwhisker in hand, but use him and the scheme to produce even more N'zoths.
So By Mid-game you should have N'Zoth spawning a 7/7 taunt 8/8 and a 1/1 with rush and cleave poison.
I really have hope in this deck and will update it as the meta is made and ongoing.
