The objective of Rainbow Dark Dragon Turbo (RDDT) is to load the Graveyard with DARK monsters in order to bring out Rainbow Dark Dragon. There are two main ways to load the Graveyard with DARK monsters. The first involves Veil of Darkness and using it to load your Graveyard with DARK monsters (however using this method makes getting DAD out a little harder if you don't start off with him in your hand). The second way involves using Monster Gate and/or Reasoning together with lots of DARK monsters that cannot be be Special Summoned by other card effects (Dark Armed Dragon, Dark Necrofear etc). This second way is not popular as the two Spell Cards mentioned above are Limited(1 per deck) and it requires you to heavily cut down on DARK support Spell Cards like Allure of Darkness, Destiny Draw,
