Every time. The game is pattern not random.
The best example use to be Hunter decks. Now its Galakrond Rogue.
Notice the same cards played over and over and over and over again turns 1 -10 or however long it takes for the game to end?
Shield of Galakrond at least once probably twice.
Zilliax going to drop turn 5 - 7.
Lackey up turns 3 - 7.
Backstab, Eviscerate and sap will all be there. Probably twice…
Togwaggle with Shadowstep coming right up!
You see the optimum top decking because its designed to hand out cards that way every game.
