"Sin Kaiju (advice requested)" Deck 2016

Playing

I'm an unfamiliar young man.
There are a lot of things I don't understand about extras and support cards, so I'd like some advice.
I used Sin. and his Kaiju to attack the opponent with high RBIs, and I added trade-ins and montage dragons to make accidents less likely to occur.
I plan to deploy Sin. and Kaiju on the field while preventing monsters from self-destructing with the effect of Skill Drain.

Strength

I would like to use 《Skill Drain》to put Sin's self-destruct effect and two of his Kaiju on my field.
I think it would be ideal if I could put KYOUTOU on the field, which is basically hard to destroy, and Sin. Stardust.
I like the fact that you can play Kaiju and bring it to your field with Owner's Seal, and you can bring it back after summoning his Kaiju with Skill Drain.
With 《Skill Drain》, even if the field is destroyed, the Sin. monster will remain and other monsters will be able to attack together, so I think I can hit consecutively with a high RBI.
Considering when my hand is full of monsters, I put in Montage Dragon as much as I feel like.
Great Beast Garzet is included for when you want to build momentum after mass deployment.

Weakness

Since I'm a beginner, I don't know which cards are compatible, which rank 8 and rank 10 Xyz, and what to do when 《Vanity's Emptiness》is activated is ambiguous.
Not only that, but I still don't really understand the basics and balance, so if you don't mind, I'd like your advice.

Customize

I haven't figured it out myself yet, so I'd like to update it as soon as I receive everyone's comments.
