1x D/D/D Kali Yuga the twin dawn overlord

Yes as you can tell they card do not just fusion summons synchro summons and xyz summons they can also do pendulum summons as well . What do you guys think about this deck?

-2 Valkyrie
-1 Cruel End Overlord
-1 Swamp King
+1 One for One
-3 Upstart
+1 Resource Management
+1 Lilith
+1 Allure
+1 Lease Laundering
+2 DD Ogre

for extra deck:
-2 Ragnarok COO
-1 D'Arc
-1 Alexander
+1 Dragosack
+1 Felgrand
AKA add more generic xyz and synchro, like Chaos King Archfiend

this build is going too "anime", and without generic cards to help it, it will fall quickly(at least from what I see)
