I dont know what cards to take out for my elemental hero deck?

Take out Cemetery Bomb. Add in Stratos, no e-hero deck is complete without the almighty stratos. Take out Fusion Sword Murasame Blade, Mask of Darkness, and Winged Kuriboh. Have About 3 Captain Gold's and 3 Skyscr's. Take out Heat and Lady Heat and probably 1 Woodsman. have 3 Polymerization. Also take out Warrior Returning Alive. You will have too many monsters in your hand. Have about 2 Miracle Fusion. take out Oversoul since you have miracle fusion. take out ceasefire, it doesn't fit together with your deck.
