"GY use Deck (seeking advice" Deck 2015

Playing

It is a deck mainly based on the concept of using his GY.
There is explosive power, but when it falls, limit cards and others will fall bang bang
The trap isn't that thick, so it's best to decide the game early.
Beasts and lizards in a bit are just draw factors
'Cause if you add too many Shaddolls, he'll be eroded, yeah
Lilo and Brotherhood of the Fire Fist are basically the main axis
Tenki can search for Wolfberg, and he can catch Brotherhood of the Fire Fist, so GY will grow to some extent.
Burg can be used quite a bit
For the time being, Luminous and others are there, so you can set up 7 or 8 synchros.
You should be able to make various movements according to the time.
It's still a sweet Deck, but please give me some advice.

Strength

4 or 7, 8 synchro with lyro
Catch 4 Eks with a Burg
Of course, 4 ex is also possible with Zepusauza

Weakness

constellar diamond, necrovalley, rift, macro
It's pretty painful if the GY has irresistible cards or cards that you don't want to use.
After that, it eats Deck at a considerable speed
And above all, Trap is fluent, so it can hardly interfere

Customize

I think that the contents of the extras are up to each person's taste
Also, I think it would be nice to add the End of the World or the Pot of Greed.
I gave up because I didn't have enough space.
I think this Deck will probably contain a variety of cards.
Please give me some advice including that
