As the name suggests, here is a deck that resolves around Number 9: Dyson Sphere. This information has been taken from http://yugioh.wikia.com/wiki/Forum:Building_a_Dyson_Sphere_Deck_centered_around_Tannhäuser_Gate The Deepsea King Lemuria one. The 2nd one.
This deck is very heavily weighed on Dyson Sphere, So it is important to get Dyson Sphere very quickly.
EXAMPLE: You have Lemuria, the Forgotten City face up on your field. You have Shark Stickers face up in ATK position. You have Superancient Deepsea King Coelacanth in your hand. You tribute Shark Stickers and summon Superancient Deepsea King Coelacanth in ATK. You discard one card to activate its effect. You summon 2 Hammer Sharks and 2 Royal Swamp Eels. You activate the effect of Lemuria, the Forgotten City, so all of your monsters become LV9 You overlay any one of your 5 monsters to XYZ summon Dyson Sphere. You still have 3 LV9 monsters on your field, so overlay them as well for another Dyson Sphere. Let's say you opponent has 5400 LP, With Blue-Eyes-White-Dragon on his (or her) field. Due to Dyson Sphere's effect, Both Dyson Sphere's attack directly for game. (5400-0)
Finally, the deck. (I am sorry that it is not neat, but I am new here and don't know so much.)

Once per Battle Step, during your opponent's turn, if this card with Xyz Material is attacked: Negate the attack (this is a Quick Effect). When this card is targeted for an attack, while it has no Xyz Materials: You can target 2 monsters in your Graveyard; attach those targets to this card as Xyz Materials. During your Main Phase 1: You can detach 1 Xyz Material from this card; this card can attack your opponent directly this turn. Your opponent must control a monster with higher ATK than this card for you to activate and to resolve this effect.
