SMEXY RIGHT

if the reason for the d.d. survivor is to do combos with cyber valley, you're better off using something else, honestly

1-2 pot of duality here wont hurt, and I like to use traps

Randomly-teched Necroface for banishing pieces to summon Lightray? Neat idea, but you may end up banishing a lot of useful things in the process. I also agree on the Survivor; yes it's a +1, but only if your opponent lets one or the other sit around a turn. If this were a D-Fissure deck, different story.
