Try mulliganing for any cards that work well with discard (you're ALWAYS going to get the discard pack as well when you can, otherwise get C'Thun - that's why we put him in deck). In first games of the run, you win by felosophy killmox and raise dead-ing it, because your deck is giga thin, late you overwhelm on board and pick if possible treasures that chokes enemy on board (snakes, cannibalism, zombies).
I got 12 wins with this deck in Duels. I had Zombies and Cannibalism as treasures which was really really broken (wins 6-11 I lost a total of 2 hp due to me being able to make a lot of board presence) but lost 2 for giga lowrolling and enemy highrolling. I also got spyglass and loyal sidekick and 2 snakes.
