as martin said, combining the sacred
beast, usable god cards (of which there is currently only one), and exodia is just impossible. you are trying to take this deck in too many directions at once, which unfortunately means you will never be able to successfully pull off any of your planned strategies for this deck. My advice would be to choose sacred
beasts, god cards, or exodia and focus on just that one strategy. though none of those three strategies, even individually, will be able to stand up against the meta (depending on your location)
