"Acoustic Zefra Please advise" Deck 2015

Playing

This is my first post.
I would like to participate in the competition for the first time this time, so I posted it to ask for advice from everyone.
At first, I thought I'd enter HERO, but since it was my first tournament, I decided to enter Zefra Deck, which I had a dream about.
Side Deck
D.D. Crow One piece
Proliferating G 2 sheets
Three cyclones
Shared ride 1 ticket
Twister 1 sheet
Book of the Moon 1 sheet
《Cursed Seal of the Forbidden Spell》one piece
《Compulsory Evacuation Device》Two pieces
《Debunk》Two pieces
This is the construction.
I'm not sure how to deal with environmental decks at the moment, so I'd appreciate it if you could give me some advice on side decks as well.
Any advice is welcome.

Strength

In addition to Zefra's search with Ciugo, Zefra's butte & Zefra's removal with Zvern, Pendulum Summon, and the deployment power of his Symphonic Warrior, this is his Deck that focuses on Synchro and Xyz.

Weakness

Vulnerable to Pendulum Monster properties, Special Summon Containment, and Exclusion.
In addition, it consumes a lot of cards, and once it is turned back, it takes time to recover.

Customize

I don't think his Deck is very helpful, but I think the Zefra Deck will change depending on what it's based on.
I think that you should put cards that you want to use more and more.
