"Use Cthulhu (suggestion)" Deck 2016

Playing

Since Cthulhu came out, I am currently using this type as a result of various trial and error.
I used Stealer and Synchro Fusionist, but he came with a simple Xyz called Zoodiac and all Hanafuda tuners can be synchronized as ☆ 2, so I tried mixing them.
Hanafuda is basically a peony with a butterfly acting as a tuner to create an Old Entity.
Sakura ni Maku hopefully doesn't use the right to summon, so it can be further developed.
(The number of flower stacking and card regeneration is under consideration)
Crystron's main role is to provide synchronized materials for the field
Use Sulfur Furnace and use Crystron as SS and Synchro material in the field
It can also be used as a means of breaking Hastor which has become equipment.
Zoodiac does Xyz to provide materials for Nutos & interferes with dragons & children are synchronized materials
It is because of her deck compression that only Zi and Snake are included. 2 child SS and Mi search in the flow of baby boar → tiger → cow X
It's a Deck that satisfies you by doing things like this and putting out Azathoth.

Strength

Synchronization is easy if there is a curtain on the flower pile and pine or cherry blossoms
Xyz can be done if there is a kaikyoku, so if you can't get a sync
If you can synchronize, you can go to Nutos
I can't say that the stability is that high, but I think it's easy to put out Azathoth

Weakness

Overall lack of firepower
The highest is Nutos 2500, so I'm considering stacking multiple Snakes.
Also, there are too few countermeasures against the opponent, and it is so fragile that it is difficult to recover with a little interference.
Special Summon Impossible will die, and 《Toadally Awesome》can't be helped
Fan deck

Customize

Flower stacking may be better with 3
Since it is easy to expand Old Entity by repeatedly hitting Hanafuda from Deck top operation
Regarding the lack of firepower, there is no choice but to insert a snake as described above or consider other methods.
To be honest, I'm stuck in this situation right now, so I'd appreciate it if you could give me some improvement suggestions.
