thanks for writing your essay, i guess
but ... your FTK version is the brickiest version I ever seen :>
U need 4 Cards in your Hand to get the FTK ... eh what?
to activate Gozuki U need another zombie in grave to banish, so U have to summon Uni-Zombie with Shiranui Solitaire (U need Gozuki for your second special summon (from Hand)), then U can discard or mill Gozuki (doesn't matter) and a Soul-Absorbing Bone Tower (ether mill or discard the opposite action of Gozuki)
U have only 2 cards who are able to mill: Uni-Zombie and Yuki-Musume, the Ice Mayakashi. For Yuki-Musume U need a Mayakashi on the field. So, U have to summon Hajun, the Winged Mayakashi with Gozuki from your Hand.
To summon the Bone Tower, U have so special summon the Yuki-Musume and mill Mezuki. Mezuki will then special summon the Bone Tower from grave.
this mean, your first 5 Cards have to be:
Hajun, the Winged Mayakashi OR Mayakashi Return IF Yuki-Musume
Gozuki OR Soul-Absorbing Bone Tower
Yuki-Musume, the Ice Mayakashi OR Mayakashi Return IF Hajun
So your deck will most of the time just brick or just synchro summon and wont be able to bring the tower out...
I mean your on a good way, if u play cards like One for One, but u cant build an "FTK-Deck" based on one out of 40 cards.
with One for One its "only" a 3-Card combo.
One for One + 1 Card to discard
Solitare OR Uni-Zombie OR Bone Tower
