Easy to play deck. Use Danger! and Dark World effects to destroy opponent's cards and summon as many high level monsters as you can. You can use Galaxy Wizard to Normal Summon level 8 or get Galaxy Queen's Light to change all your monsters to the same level.
You can use Astral Kuriboh to give your XYZ Number monster protection from destruction.
With Astral Kuriboh and Galaxy Queen's Light you can even summon Number 92, so you could Special Summon it from GY if it gets destroyed (negated on the field and then destroyed)
Just summon Number 97 and use it to summon 92 or 38.
If you go 1st, it's good to summon 92. If you play against Eldlich, you won, as you will just banish everything they set and on your turn summon Number 100 for 18k damage.
