Jade elemental rogue has been serving me well enough in the current meta, and with Valeera the Hollow I think the deck might just be good enough to see real play. The Deathknight for rogue means you can play an extra jade spirit or servant of kalimos or vilespine slayer. That is a huge amount of value and might push the deck to be able to actually take down control decks more consistently, and against midrange it provides an extra turn where they can;t kill you, allowing you to follow up by reversing the boardstate with all the tempo removal rogue has.
