I think this deck will be a meta-defining for rogue. Maybe a counter for Malydruid and other non-fun decks hahah. The idea behind this is you play the pogo-hopper and shuffle copies of him to the deck with Lab Recruiter and Baleful Banker. Saddly, there’s no cards that draw pogo-hopper to you in a certain, so, if you don’t draw him on the early to a midgame, you probably lose to any midrange deck. The dream is to get a lot of Pogos with Sonya’ s effect or begin with a big early game, but i think this deck works better as a midrange. Remember, the only win condition on this deck is the Pogo being bigger turn-after-turn, so, if you mill the two original copies before you copy them, you probably will lose easily. Knewing that, never play Pogo-hopper without a tool with it, so, never pogo-hopper turn 2. Sprint and Myra’s Unstable Element will help you to find the new copies on the mid/late game.
(Only Theory for now, there’ s more 4 days left for the expansion launch)
Agaist Control: I think against control you can win using the deck real mechanic, that is, using the pogo-hopper effect. But remember, different from Jade Druid, this deck is not infinite madness, so you cannot make a late late game. But, against Malydruid for example, you can win easily if you draw your tools early or during the midgame, as Druid has a lot of problems to face a big board. Against Evenlock will depend of your early tools for control the game, but you can try change some cards to put more tempo plays.
Agaist Midrange: As a midrange too, you need to control the board and get the more tempo you can, so Edwin, Valanar, Eviscerate and the cost-1 elementals can help you to control until you get the big pogo-hoppers.
Against Aggro: I think this is the most hard one, because the deck focuses on play a good mid or late game, so against odd-pala or rogue you will have a lot of problems. But maybe cutting of the Brewmaster and the Banker for Doomsayers and SI: Agent/Fan of Knifes can help you to control until you get Valeera and hoppers for the ultimate win.
