3 MST

1 Torrential tribute

1 catastor

1 Trishula

1 Scrap dragon

1 Librarian

1 leviair, the sea dragon

1 Gem-Knight Pearl

2 Utopia

2 Steelswarm Roach

1 Vylon Disigma

2 Number 30: Acid Golem of destruction

1 Number 16: Shock Ruler conqueror of colors

1 The Sacred Hyades

Both Utopia and Roach are staple in the deck since Rank 4 is the easier xyz summon you can make. Gem-Knight pearl let you destroy stardust or another 2500atk monster. Whereas Nº30 replace Leviathan dragon in the OCG, don't worry for the burn damage you could suffer, if you manage to keep Nº30 on the field, you are probably wining already. On the other hand, Leviair is really important since one the worst enemies of the deck is bottomless trap hole.

The two best card on your extra are Nº 16 and Vylon Disigma, wich actually are the two best generic xyz monsters on the game (In terms of brokeness). And yes, Librarian is there because I want another lv5 syncro to fight.

In each new pack of the zexal era, new xyz monster will came up and this extra will be stronger.
