I'm assuming that you are going to be dropping Dark World Dealings once everyone and their mother starts running Dark World? Seems like the OCG builds run Dark World Lightning more than Dealings.

If everyone starts running dw, which imo i dont think will happen on account that i think everyone is still going to be on agents and plants, i will prolly be cutting out, DWD, Morphing Jar, and Card Destruction

Yeah it's really only the mirror match that I'm concerned about. I just feel like if the Structure Deck is available you are going to see some other people playing Dark World.

Testing has been going well though?

Good cards would be like

Dragged down into the grave
Eradicator Epidemic virus
Tour guide - so you can make xyz monsters.
Fabled Raven - so you can discard goldd or sillva and sync into a lvl 8.

You'll want the fabled ravens. Dark Deal would be optimal, but you run low monsters... consider gozen match for your side.
