This deck is a lot of fun to play if you like to gamble. There will be some really extreme highs and lows.
Most important extra deck monsters are: Number 60: Dugares the timeless (you're gonna wanna draw from him as soon as you can), Fusion Grapha, Clorless (if going second), Number 38: Hope Harbringer (for some spell negates), and Apollousa.
Notes:
Genta and Gates to the Dark World. Gates is a soft once per turn and Genta's search for Gates is not once per turn (Only the special summon is).
Ceruli and Sillva. Brutal combo if going first.
Grapha and Reign's Special Summon from GY are not once per turn so abuse it to summon Number 38 or to get enough damage on the field.
