Rate/Fix Jurrac Deck?

First, take out the 2 Tyrannus, and replace them by 1 another Titano. Tyrannus is weak compared to Titano, u need Dark Hole( replace Lightning Vortex) with Smashing Ground and Book Of Moon in your deck, also include Jurrac Velphito in your extra deck, if your opponent play a card like Marshmallon, for example, what should u do? A great combo with Book and Velphito, use Book to change 1 monster( Like Stardust Dragon,etc.) into face down and attack it with Velphito. If u run 3 Jurric World then don't put Solidary, use these cards. Last suggestion, add Mystical Space Typhoon and Giant Trunade.
