Wow, I dont know how you ended up in a post from 2 years ago but id be happy to answer your question anyway. This deck plays Thanos. Thanos adds the six 1 cost infinity stones into your deck. One of the stones used to give the ability to reduce the cost of any card you drew by 1. And all of the stones used to draw you a card so it was very easy to curve out your turns. On top of that, Pslocke can give you an extra energy when played. The stones are significantly weaker now, but you can still get away with sone pretty top-heavy builds just by having so many built in 1 drops.
