Now it's time for Blade. I still have to watch it, but, once again, they explain their science quite nicely. And, once again, tachyons. That big, floating card-thing that appears after a card is turned up is an unstable tachyon field; that's why it is able to block attacks. The Rouse Cards are like keys, determining which tachyon field to activate. Each tachyon field fuses the user with a different set of Undead DNA, or which set of Undead DNA. Passing through the field warps the user into a reality in which the Rider armor is set up on them. This process seems to take seconds due to the special properties of tachyon particles.
