This deck functions through using your opponent's deck against him or her. There are only three creatures in the main board of this deck. Instead of creatures this deck uses planeswalkers. To win you use the creatures in your opponent's library. Alternatively, you can mill them out if there are no creatures in their deck. There are three complete playsets of different planeswalkers that serve a purpose.
First and foremost is Ashiok, Nightmare Weaver. The deck uses four Ashiok, Nightmare Weavers to play an opponent's creatures against them. If there are few creatures in an opponent's library and you can't kill them with their creatures and you can't seem to find Stormbreath Dragon then, Ashiok, Nightmare Weaver can be used to slowly mill them out.
Next we have Jace, Architect of Thought. Jace is used for card draw. His -2 ability allows an opponent to separate the top three cards in a library into two stacks. You choose one of these stacks to go into your hand while the other goes to the bottom of your library. Additionally, Jace also reduces the power of an opponent's creatures when they attack. Jace, Architect of Thought's ultimate ability can also use opponent's cards against them.
Finally, we have the Swiss Army Knife planeswalker, Ral Zarek. All three of Ral Zarek's abilities are extremely useful. His +1 can be used to untap one of your lands or other permanents while tapping an opponent's permanents. While his -2 can be used as additional removal. His ultimate ability (-7) gives you extra turns which works well with the other planeswalkers in this deck.
The rest of this deck consists of counter spells, various removal and burn spells. The removal includes Hero's Downfall and Ratchet Bomb. There are three Stormbreath Dragon's in this deck which can used in case an opponent's library does not contain creatures to use against them. Stormbreath Dragon is hard to deal with and can deliver damage in the air to an opponent late game.
