I hope you dont mean spellbook with silent magician as brain required.
It is among the easiest decks in this game atm.
Spellbook rotations are figured out in a few min.
Silent magician removed all the brain that normal spellbook required to keep its monsters alive.
As silent magician is so durable.
Vampire requires a bit more thinking than Fur Hire.
Plus, it's not cheap at all. Running Vampire in Ranked pretty much requires you to get 2-3 Gozuki and Samurai Skull.
Not only Gozuki is an UR, but also, Gozuki and Samurai Skull are in two different main boxes. So that's three boxes (1 mini and 2 main) you have to open.
This deck is anything but F2P. Even if you only use one Gozuki, you still have to search through Generation Next and Resonance of Contrast for Samurai Skull and Vampire Grace. Getting 3 cost rare cards easily 100 packs on avg minimum. On top of all the searching through Empire of Scarlets and Crimson Kingdom for Gozuki... one of the most expensive decks tbh. NOT F2P AT ALL.
True my I'm f2p and my 25 card dmoc tricky spellbook needs alot of thinking and they released this p2w version silent spellbook which is super easy to use and too strong my gems on that vision box is now a waste just like sylvan and fur players
