About my idea of cutting Leylines, I'm thinking of playing Darkblast's instead of them, much better than Leylines I think!
I saw many people playing Contagion, but removing a Black card from your hand early in the game isnt very fine most of the time.. And Darkblast is also a Dregde 3! -1/-1 looks good enough against most creatures you hate, like Yixlid Jailer, Mogg Fanatic, Confidant (they find there anti cards faster with him) etc.. Of cource most of the time you dont have Bridges in your grave, because these creatures come turn 1/2, so that isnt even a problem..
Withered Wretch is still a problem, Contagion works against him, so should only he be a reason to run Contagion? Why doesnt Dredge and cost 1 black card..
