How about a 3rd Secret Village instead of Terraforming?

Yes, I know Terraforming seems better because it thins the deck but it will be a dead draw if you get the 2 Fields before. If it was another Village you wouldn't have that risk, and you can fix any dead Field Spell in your hand with Monk anyways. Altough you can fix the dead Terraforming with Monk too, so I guess it's up to your preference.

 

A Gravekeeper Spy engine can help you to increase the monster count, just in case not having enough Spellcasters to keep Village active becomes an issue.

 

I Was about to suggest Alchemic Magician for your Extra Deck as she is one of the few Spellcaster Xyzs useful for keeping Village active, but then I remembered Masquerade Magician is an Spellcaster too but arguably better.

 

Do you really need 2 Papilloperatives? You could drop 1 to run other Xyz, such as Abyss Dweller for locking the opponent's Graveyard.

This my irl deck, and I only have 2 Secret Village. I might try Spy, since it seems pretty cool. I was not aware that I had 2 Papilloperative in there.
