This deck is a bad idea, but maybe bad enough to work. The basic idea is to abuse Pogo-Hopper like it’s a Jade Idol and keep on making larger and larger Pogo-Champs. Eventually your win-condition is to destroy your deck with Myra’s (or use it to accelerate the end game) and fill it with Pogo-Hoppers thanks to Lab Recruiter. Once your deck has some, you can get additional copies thanks to Mimic Pod. Sonya gives you extra copies if you trade them in. Double Shadowstep is debatable but gives you extra Pogo-Hopper buffs or the ability to Shadowstep Sonya, which is pretty good. Valeera gives you extra cards as well, which is always sweet.
Fal’dorei Striders are also just great in any Rogue deck that aims to draw a lot of cards, and they’re a nice backup win-condition in a pinch, since they synergize well with Lab Recruiters and an empty deck.
Everything else is pretty standard. I decided to add one copy of Vanish; not only can it give you extra Pogo-Hopper procs, but it’s also useful the turn after you play Valeera the Hollow.
