Rate my Yu-Gi-Oh! deck?

hm. well. the deck doesnt have a theme, because you have exodia, obelisk, slypher, and winged dragon... it combines several archetypes that arent supposed to be combined. it will be pretty hard to summon any of the god cards as you have almost no monsters you can normal summon. (as a reminder, marshmallon is limited. u can only have 1 in ur deck)
