The goal of the deck is to use Doll and Fairy to keep your opponents stuff down while you chip or mill for game. (Most likely chip damage). Also you depend on your field spell a lot but hopefully you go into time before your opponent can side s/t hate.
Non Ghostricks in the Main Deck:
Mystic Mine: You play 4 copies of metaverse. It can be a free win going first and can stall so you can get resources. It's just nice to have.
Needle Ceiling: It Blows up your opponents board but not yours since it only effect face up monsters
Drowning Mirror Force: Your opponent is going to attack directly most of the time due to the your field spells or you bricked which resulted in a t set pass. Either way it's a good way to remove stuff but it is vulnerable to s/t hate.
For the extra deck Break Sword is there because good rank 3. The links are generic. They're nice to have but if you want to run extrav then I recommend swaping 2 of them for another alucard and a socuteboss.
Other options (All of these can replace Needle Ceiling or Drowning if you want):
The Rock: It's needle ceiling but a handtrap. It only tributes face up monsters meaning most likely your not deleting your stuff.
Battle Fader: It's a better lantern but not searchable and not recoverable.
Pot of Extrav: It's a plus one. If you want to use it then I recommend taking out a skeleton and jiangshi or 2.
Titanocider/Lost Wind: Negates stuff and makes your opponent suffer more. What's not to like?
Gozen Match: This is a side deck card. I only recommend this in the side.
