Please rate/give advice on my yugioh deck?

ahhh... the advice is to grab a structure deck or 2, because just about any of them is better than this. frankly, a random pack deck don't work, ur deck don't have enough combos(speciallization) nor enough power(great white etc is sorta out dated) after that, u can do a bit of power replacement to the structure, but stick to the structure for now, u won't be able to top format for a while until u get the feel for combos first... keep deck size under 45 if u can, there are very few exception to that size rule(galiator and crystal beast being 2 of the few)
