PROS- THIS CARD IS LIKE A BOOK OF MOON
CAN STOP CARD WITH FACE-UP EFFECTS
GREAT FOR RESETING CARDS WITH FLIP EFFECTS
Cons- Spirit typical -returns to you hand
CAN'T BE SPECIAL SUMMONED
LOW ATTACK

POSSIBLE COMBO'S:
Special Summon Magical Scientist use his effect to Bring out fushion Monster, Summon Tsukuyomi flip that monster Face-down, Card is no long subject to Magical Scientist effect. Most Fushions have strong atk/ def so it will survive a turn.

anouther thing to use this card is for jinzo, or some high atk, low defense monster like that,except it can't beat some of those monsters atk, you'd have to find a diffrent monster to do that

7.5/10 for spirit decks

5.5/10 for others

I'd stick to book of moon though
