Well, he is faster than Mecha'thun in Myra's Unstable Element rogue decks whatever that means. I guess if you bounce it somehow, you might get a stronger neutral Alana, though that's pretty slow and some decks (control priest, warlock, warrior) will save their best AoEs for that turn.
We need to see the rest of the cards to see whether the Chef can be included. At least CheeseEtc will get an inspiration for his Chef class.
It is hard to think about this card viability yet, pirate rogue is kinda already a thing, if we get engine draws like Elven Ministrel this might be a thing, considering a 7 mana 42/42 is basically game if you are not a warlock.
Then again tempo rogue loses a lot this expansion.
