[Tavern Brawl] Unstoppable Mill Rogue

Turn 3: Preparation + Evasion (or earlier if need be), Counterfeit Coin + Spirit of the Shark. Turn 4: Coldlight Oracle + Shadowstep + Counterfeit Coin + Coldlight Oracle + (...) until you clog your hand or opponent fatigues to death. Preparation + Evasion will ensure that you'll endure, in order to finish them off next turn. This deck simply can't lose!

Don't be greedy keeping a Preparation, but play it alone every time you draw it while playing the combo, so that you draw the core combo cards (Counterfeit Coin, Shadowstep).

I play Spirit of the Shark over Brann Bronzebeard for the stealth mechanism. You can run Shiv instead of Evasion if you want, but it won't guarantee the victory against Priests. The original version always beat "mirror" matches, simply because you won't take any fatigue damage.
