Delg's effect is really awesome while Dimensional Fissure and/or Macro Cosmos is face-up on the field. Since it's an effect and not a cost, it already works but it removes from play the cards, not send them to the Graveyard. Pot of Duality is also good here since I not SS too much but it gives me an advantage.

It's really confusing when the Pic and the list don't match. The List is better, so I'll fix it:

-1 Cyber Dragon OR Book of Moon OR Return from a Different Dimension

+1 Soul Exchange

Looks pretty good. Something to consider (if you play match duels with this) would be to only run 4 Macro/Fissure, since you can get it much easier with Duality and not everyone Mains both their MSTs. Then, you can add it back in game 2, expecting more backrow hate.

I hope that helps!
