The point of this deck is to (1) get Morphing Jar on the field via Gold Sarcopgagus, Mystic Tomato, Sangan and Giant Rat.
Then (2) give control of Morphing Jar to your opponent via Creature Swap, Mystic Box and Shien's Spy.
Finally, (3) spam spells that flip face-up and flip face-down Morphing Jar to mill through both of your decks until both of you have very little cards.
Then (4) use Card Destruction, Needle Worm and Book Of Eclipse's effect during the End Phase to make your opponent Deck Out first. This can all be accomplished in 1 turn, and if you're lucky, you can win on your first turn. Hallowed Life Barrier is used to stall until you get Morphing Jar, and The Shallow Grave is for backup incase Morphing Jar finds itself in the graveyard.
