Rate my Exodia Deck from Yugioh?

Your exodia deck is a long stall deck, unless u can gather the card of safe return, + 2 Manticore of darkness which can end the game, but since you have no ways to get those cards except drawing them, this is a long stall deck. You can add a gravity bind to the collection. A way to get manticore of darkness out faster is using generation shift or next to be lost. If you are playing a long stall, this deck is fine, but if you are going with the manticore loop, get more cards supporting the loop. Add another card of safe return, so you can get the require cards a bit faster. This is all i got to say. If you like the stall deck, this deck is balanced and good. Hope this helps you!
