Ghostrick is famous for being the worst at doing their own XyZ monsters. So, what about we dont do them ? Thats the whole point of this Deck. This Deck plays like Guru control except its fun ! Your main objective and way to interrupt is to flip your opponents monster with stuff like Sol and Luna or Destructive Daruma Karma Canon which help you flipping your slow Ghostrick monsters. Siren act as a wonderful searcher : if you need an interruption, take Ghostrick or treat, if you want a reborn, take Shot, you need one of your fields, take em ! Nekomosume is also a great card in this Deck, making almost every Deck twice as slow and giving you tempo.
But you might wonder, how do we win ? Thats where the last cards come in play. The best card in this Deck without a doubt is Ghostrick Night. This Trap card has the simple effect to prevent your oponent to flip monsters. This might seem useless, but this whole Deck is made to flip your opponents monsters, which will eventually end up in youre opponent having no space to summon anything. And then, thats where your field spells come in play. These card allow both players to attack directly if every monster their opponent controls is face-down, allowing you to slowly - but surely ! - to kill your opponent.
Since you dont use your Extra Deck very much, Pot of Prosperity allow you to take the piece you need to complete your hand. Finally, Terrors in the Hidden City is a nice tech card that protects your backrow and your set Ghostricks and can allow your Ghostricks to walk over big boss monsters easily.
At the end of the day, Its still a Ghostrick Deck and you cannot make magically this Deck great. But this one can work quite well against quite powerful Deck, just dont be afraid of bricking...
I hope you liked the Deck, and have a nice day / week / month / year / life !
