Well, I'd add:
-Allure of darkness
-3rd Macro
-Golden Homulcous (scout planes and surivors make him easy to summon)
-A 2nd helios
-Another gravekeeper's
-DD warrior lady is unlimited now? wow...
-Morphing Jar 1
-Stardust dragon
-If chimeratech isn't the focal point of the deck, I would'nt put in either. If he is, then run dna surgery and super poly.
-A 2nd prime falcon
-D.D. Dynamites (you may not really need prime material dragon unless you run into burn decks since Marco likes stuff out of play.)
I'd scratch:
-Cat of ill omen
-Soul exchange (unless you really want a gay combo you can use with it
)
-Future fusion
-1 D.D.R.
-Marauding captains (I prefer spell striker personally, but he's debatable)
-A Zaborg. Switch for a smashing ground or something.
I didn't look at the extra deck too much because i dont know too much about them except chimeratech, goyo, iron chain, android, thought ruler, and black rose. I trust your judgment on them.
The only two things you may encounter are speed and space in S/T zones with the deck. In which case, only set 1 macro at a time. since necro resets everything, you don't have too much to worry about. and the gravekeepers help with the speed of the deck to slow your opponent down. Also keep in mind degerate circuit makes you pay, so I'd avoid running it. I ran a crappy deck with it a while back and i lost every match due to suicide. a spell economics deck would make it a beauty but besides that, it's better things available.
All in all, I'd say it works, but just a few things i'd tweak.
