Mulligans
This deck aims to overrun the opponent with Pogo-Hopper, cards stolen from Academic Espionage, and Tess Greymane.
Early game: Try to survive until you start to gain tempo. Fire Fly is the best choice for turn 1. Use Backstab and Sap when necessary. Play Pogo-Hopper when you can follow it up with Shadowstep or Lab Recruiter. Augmented Elekk is okay to be played on curve. Fan of Knives is good to play, especially when combined with Preparation and Edwin VanCleef.
Mid-game: Play Elven Minstrel to draw your minions. Once you are holding Academic Espionage and some combination of Lab Recruiter, Pogo-Hopper, Augmented Elekk, Fal'dorei Strider, Gadgetzan Auctioneer, and Tess Greymane then you can play Myra's Unstable Element.
Late-game: After playing Myra's Unstable Element, shuffle cards back into your deck using Lab Recruiter, Augmented Elekk, Academic Espionage, and Fal'dorei Strider . Cycle through them using Gadgetzan Auctioneer. Finish the opponent with Tess Greymane.
Utility: Sonya Shadowdancer can be used whenever there are minions on the board that will attack and die. Vilespine Slayer is included for single-target removal. Vanish is useful for preventing the opponent from building a board and for utilizing the various battlecries in this deck.
