Edit: I simply replaced Malygos for Ysera. Much stronger option, Malygos doesn't work well on the starting hand or too often I would just draw it in a way that I wouldn't be able to apply its potencial. Saw some combos now and then, but Ysera is the much better option, keep both Grand Archivists, still standing strong on the meta woop woop.

Oh, and yeah! Giggling Inventor definitely survived the nerf.

I called this deck Luna's Voyage, because I played a few different variants of the deck for 3 days straight, until I got to this one, that proved the most effective. I was avoiding using cards like Giggling Inventor, because I don't really like the card that much but it works incredibly well here.
My point was to make the card Luna's Pocket Galaxy work, as I fell in love with the card before the expansion came out and I got a golden one in a pack😁.
I'm now steadily climbing with over 55% win rate , currently at rank 5 from 18

This is the most fun deck I played in a while, I hope you enjoy! Don't be afraid to ask any questions and/or make suggestions. Or requesting a guide. Don't forget to vote!

Just a quick hint as for the mulligan, the only thing you need to worry about with this deck are the combos, and preventing as much damage as possible in early game(aggro). You're going to be trading a lot, but sometimes the deck is gonna feel a bit aggroish.

Don't be fooled by the curve, the deck has incredible synergy with the Bright-Eyed Scout.

Always keep the low cost minions, and always mulligan Blizzard and Flamestrike, you get em with the Raven Familiar anyway. And as it turns out those can be more useful in the late game and have amazing synergy with the Grand Archivist, specially when it comes with a Malygos in hand with cost '1', or a '9' cost one with '1' cost Grand Archivist. Always mulligan Luna's Pocket Galaxy unless you're absolutely certain you're playing against control.

I was looking for a slot to include Ysera to make the deck even more interesting. The available slot as suggested by Tomonium would be -1 Grand Archivist. Ganbare!
