I really dig the deck. In fact, I am planning on making a similar build for myself soon. However, I have some questions on your decision for some of the cards.
I understand running Hiruko TT, as he is searchable with Sasori and can use Tetragram himself. However, I am kind of confused on your decision to put one Hiruko GA in here, since his effect of being discarded will only end up putting crow in play. Also, I was wondering what Sand Anbu is doing in here. He is a decent manipulation ninja, but I cannot really see the use for his effect in this deck.
I'm not trying to sound jerk-ish, but I just wanted to know what the intent of these specific cards are for the deck.
