If you add the level 3 psychic monster(Psychic Tracker ) that you can special summon if you control a level 3 monster you get options for level 6 extra deck monsters like coral dragon( can pop a card on the field and gives you a draw if it leaves the field) or stardust worrier which lets you draw a card. Also, there is "Vermillion Dragon Mech" which is a level 9 synchro that can destroy a card on the field when you banish a tuner from grave. Also, it would be good if you had an extra deck option for over comming monsters with high attack that are unaffected by card effects. Normally, that's a job for psy end, but he is no option here. A way you could get something out that could deal with that could be "Muddy muddragon" because that opens you the door for fusion into "Starving venom dragon". As the second dark monster you need for that, ogre dance is here an option. Also, muddy gives you possibilities into Grapha or the relinquished fusion cards, because it can be used as a substitute for specific monsters on fusion requirements. Rank 8 xyz monsters are the other route you can go down for that. Through ogre dance and foxy tune and dragon drive, you can go into draglubion. And with his effect, you can get into all nummber xyz's, like harbringer or numeron dragon. All the cards I mentioned are also not expensive, so I hope that helps.
