My new yugioh deck please help?

when you get blue eyes toon dragon summoned, your life points should be lower because of toon world, play megamorph on him. He's now at 6000 atk. Then play Twin Swords of Flashing Light - Tryce on him, he loses 500 atk, but he can attack twice. Pay the 1000 for him to attack twice, and that's game because you dealt your opponent 11,000 damage!!!!
