Mimic World: The Cards have abilities which help pull cards that are mirror images of themselves out of the deck to activate abilities found on the card pulled out of the deck other card. So for example one card would have the ability to pull its mirror image (another card with a different name and the reverse of the art work found on the other card, with a variation in the colors between the two cards artworks [where one is blue the other may be orange]) out of the deck, and in turn an ability found on the card pulled out of the deck would activate granting some sort of bonus to both cards. Mimic World focuses on the left and right rather than the center, while the world does include cards which could be used to fill the center up. The weapons are all in pairs (their is only one card but what every weapon shown on the card is doubled so that the artwork would contain 2 of any weapon. The world would also have the ability, through the activation of a spell card with the right cards on the left and the right of the field, to play a stronger card from your hand into the center while erasing the the other two cards from play. However because Mimic world focuses on the left anf right for strong attacks the center is often left open. So While the abilities are strong the fact that you are forced to in most cases to use abilities leave you center open makes up for the overpowered abilities (even though they are not that overpowered it still balances out the abilities and makes the world more fair to play agaist).
