General Mulligans
Dig and Swashburglar are standard turn 1 plays, and Daydreaming Pixie on 2 is extremely strong. Ideal curve would usually be Dig/Swash on turn 1, Pixie on turn 2, Shack on turn 3, Espionage on turn 4, then hopefully pop off on turn 5 by activating Shack.
"Health" Drink/Fan of Knives should likely be kept in faster matchups, along with Thalnos if you happen to get either. You won't often be able to pull off the perfect curve even if you have the cards in hand, so you'll have to work to stabilize first before you can play Espionage and Shack, as they unfortunately require us to sacrifice tempo upfront.
This deck is built around Agency Espionage, Knickknack Shack and Snatch and Grab, as well as the Warlock cards Eat! The! Imp! and “Health” Drink.
Snatch and Grab is extremely strong removal in the current meta, and Agency Espionage allows us to shuffle 10 cards (1 from each of the other classes) into our deck, with all of them costing 1 mana. As such, they can be easily cycled through with Knickknack Shack for a huge swing turn (though this does require a little bit of setup). And although Agency Espionage is a very RNG-based card, it will inevitably provide both value and tempo rather consistently, given the volume of mana that you can potentially have discounted over the course of a game.
Eat! The! Imp! is extremely strong draw, only requiring us to sacrifice a single minion and 2 mana to draw 3 cards, and “Health Drink” gives Rogue a consistent removal + healing option. 2 copies of this card allows us 6 activations, and potentially restoring 20+ health in a game with spell damage.
Daydreaming Pixie is a very strong card, providing generation of Nature spells from all classes (and most of which are useful), and Petty Theft serves as the most efficient activator for Snatch and Grab. The deck is rounded out with Rogue staples. Tess is included in this list as an additional win condition for slower matchups, but she is pretty unnecessary in faster ones. As such, she can be swapped out for something else if desired.
