I noticed something about Blood-Queen Lana'thel that I don't think most people caught onto, which is her activation. Her attack gain isn't based on a battlecry, she simply has the additional attack unless silenced. This means that Cruel Dinomancer can summon not only a 12/12 Deathwing, but a _/6 Lana'thel who can regain you a lot of that health loss that puts these decks at risk, since you have to draw so much to have cards to play.

I don't think Discolock will be a tier 1 deck, since there's so much RNG involved, but if more cards come out that have great value for the deck itself, like Silverware Golem and Cruel Dinomancer, the payoff could eventually outweigh the risk.
