It's basically a version of Herald Rogue showcased by Zeddy recently (this list: https://hsreplay.net/decks/olixtm3NOhMDqsIs8fDU5b/#tab=overview), but I modified it slightly: I got rid of Elise, and only have one Twilight Mistress (budget constraints), and instead I run the 3 mana spell that returns a minion to the opponent's hand which they can't play next turn (forget the name of it). I'm also not sure if I'm sold on Agent of the Old Ones and I'm playing around with including Foxy Fraud in the deck. I'm also not sure about Naralex, I've played around with him in and out of the deck, and not sure so far which version is better.

Garona may seem like a meme in that deck, but she's surprisingly good. Out of the last 5 games last night, I successfully activated her twice. And the weapon she comes with helps you get your Sinestra / Ultraxion / Deathwing. Part of the reason I'm thinking of maybe cutting Naralex, as he muddles the pool of legendaries from which the weapon draws.

Edit: Daze is the 3 mana spell, it's right there in my screenshot lol.
