Now now, if u enjoy stealing, and u feel that rogues are about that, then this is your deck, expensive and fun, can make any champ run. 

Cards that can be swaped and options 

Scarab: Doomsayer

1 SI:7 agent= vanish (keep one, its pretty powerfull)

First rounds: Fire fly, scarab, fan of knives, thalnos

Mid game: controll mid game with combos and spells, u got to stall as much as u can...well.. unless u can get necrium out and cairne on a cleared board, wich is mid game wining most of the times.

Late: get valerra and own ur opponent, it s just op, otherwise, hold up until u get espionage and sprint.

Special combos: remeber u can get prep and academic on turn 1, using combo cards early  can result in extreme destruction, allthough is quite rare, and it can go wrong from time to time, but still is op, drawing 4-5 cost minions at 1 cost, can be game changing, aswell as geting 7 + cards , usually people surrender. But, the opness lies not only in stealing, but  in properly using combo cards. Also, Blightnoozle and sonya can pack a punch, remeber that. Necrium blade and cairne/Myra with a good battlecry can own the mid game. And last but not least, the spirit, use it wisely.

The rest is up to you, try it out, you'l be amazed.
