I like how you made Adder a Recurring Nightmare target.

Also, a minor thing, change the Xyz's name to Vennomonydra? I think it fits better with the name scheme, and (imo) rolls off the tongue easier.

Also, I think you should do more support like [url="http://yugioh.wikia.com/wiki/Snake_Deity%27s_Command"]Snake Deity's Command[/url].

That was what I was aiming for with Order.

Also, added a SS-United for these guys.
