Rate my yugioh deck please?

Take out the Gods. Sacrificing 3 monsters for a summon is just not worth it especially for Ra and Slifer. Make sure you have a good balance of monsters that you can sacrifice for the tribute monsters otherwise your going to be sitting with Blue Eyes in your hand and no way to get them on the field. An alternative you might consider if you could get a Blue Eyes Ultimate Dragon and Polymerization to use would be to fuse your 3 Blue Eyes from a strategy standpoint you would probably be further ahead to make this a Dragon Deck revolving around cards from that archetype.
