How good Is this updated exodia deck? further help and fixes appreciated.?

take out diver's, they seem too slow, add in des lacoodaa xx3 instead, mallet is meh, I advise just 1, the dark door isnt great stall without somethinng like scrap iron or so, cup of ace is just terrible, avarice isnt great nor is back up, avarice is more of a side, add another upstart goblin, defense draw is meh, add in limit area B, another threatening roar, arcana the fool instead of spirit reaper or so, add i wall of revealing light, another messenger, nightmare steel cage, take out exodia, it doesnt help your deck, etc etc
