So, here's the thing. Have you heard of Genesis Dragon yet?
Genesis Dragon
Level 6/LIGHT/Dragon/Effect
Once per turn, you can send 1 Dragon-Type Monster from your hand to the Graveyard to add 1 Dragon-Type Monster from your Graveyard to your hand. When this card is sent from the field to the Graveyard, you can return all Dragon-Type Monsters from your Graveyard to your Deck.
This will help you set up the Vandy plays that you are looking for, plus it's a light monster which makes Chaos Sorcerer easier to play.
I'm really not crazy about Dark Horus in here so
-3x Dark Horus
+1x REDMD (don't worry if you don't have it, promo'd at the beginning of March)
+1x Vandy (I'm sure Landon will loan you one if you ask sweetly)
+1x Genesis Dragon
Now, that did drop your Trade In targets by 2, but that is workable with the Genesis Dragon. The deck needs some better opening plays
- 3x Upstart Goblin
+2x Ryko
+1x Morphing Jar
Morphing Jar is not the best opening play, but it can be used to set up for The Dark Creator alot faster as well as pair Darkness Metal with a Wyvern for you. I feel like it needs something else, but I am having a total brain fart right now, so I'll get back on this later
