I have only tried his in a Max Stampede stadium because I haven't got my attack stadium deliveird yet but the best two combos I have found are :

1: Dark Wolf SW145 (In Defense) SD

2: Poison Serpant DF145 FS

The first one is just pure awsomeness.

Every single part you listed is outclassed. Dark and Poison, you will find, do not perform well at all against a multitude of other parts (such as Earth, Gravity, Burn, Lightning, Basalt, Screw).

Please read "The State of the Customizations" thread. This will be closed.

PS The combos are pretty bad...

I make idiotic posts sometimes, and I apologize for any of them. I'm still trying to be a more constructive poster. Feel free to correct me with any of my posts through PM or in the thread if it's not off-topic.
Please keep in mind when reading my posts that I know little to nothing about the current metagame and Zero-G.
