Rate/Fix my Dark Creator Return Deck?

You did not share what it is exactly what you want to do, so I'll give some basic tips. The Dark Deck is a deck that removes monsters from play for powerful effects, and utilizes cards that can make use of the monsters that have been removed. Now, in this deck you are most definitely going to want to have multiple copies of D.D.R Different Dimension Reincarnation to get back monsters you remove; two is a bare minimum. You can also use Escape from the Dark Dimension, but as a trap you won't be able to play it on your own turn to summon your monster out of nowhere. Return from the Different Dimension is good to bring back many monsters for a surprise victory, but it's costly. Honestly, there is a lot of fat that can be trimmed to make way for cards that really help this strategy, such as Penguin Soldier and Winged Kuriboh, but there are more. A card I very highly recommend to help this strategy is Dark Nephthys. It removes two dark monsters in your graveyard from play, to give you a special summon on your next turn, and gives you a Mystical Space Typhoon bonus to boot! Follow up that play with D.D.R., and you can have something like your Dark Magician of Chaos back up and running, and you'll get a spell from your graveyard to boot! Feel free to e-mail me if you would like some more in depth suggestions as to what to remove from the deck, what to include in the deck, and why.
