This deck wants to resolve Pyxis and win the game in the round it does or atleast the next one. It does so by exiling cards that do cruel stuff when entering the battlefield such as Gary, Abhorrent Overlord, Master of Waves and Clone. It also steals their cards with Specter and Ashiok in the early rounds. All the cards are permanents so we don't waste our Pyxis.

My only defense however is the Omenspeaker which also makes sure I exile the proper cards with its scry along with Thassa. I started with Phalanxes too but they have been demoted to sideboard. Disciple of Phenax was once in the deck too but got scrapped for Master of Waves when I splashed a bunch of blue in the deck.

Sideboard is just fun creatures with ETB effects except Returned Phalanx which has saved me countless times in limited and is here to defend me against aggro.
