Your deck seems to serve a couple of goals: synchroing, targeting and destroying of your opponent's cards, and using the three Egyptian Gods next to each other. Like mentioned, use some good tribute fodder engines, like frogs, giant germs, mingle, momonga, pick one Egyptian God you like best (personally, I would go for Obelisk, since he's the most powerful IMO) and run that one three times. An Egyptian God deck can be very good and powerful, but make every card in your deck (except for the regular staples) serve the purpose of summoning your God as quickly as possible. And add enough staples to prevent your opponent from dark holing your God (Dark Bribe fex). And if you still decide to run all three of them, be sure to run Horakhty as well.
