Okey, some major changes to the deck.
Machine Duplication: A lot of people say it's a must in this deck. But as I don't main Cyber Valley, it means I only have 3 targets for it: the 3 Cores. Plus, Cyber Dragon is often banished by Network, so it's pretty inconsistent in my opinion and not worth running.
Cyber Valley: Another card people seem to like in this deck. I tested it, but it's kinda slow, and the stalling is not worth it imo. I may try it in again, perhaps in place of a Upstart...
Foolish Burial: It's important to have a Cyber Dragon in grave at times, as cards like Overload Fusion, Repair Plant, etc., use it. But it's just a test and I don't know if it'll stay
Overload: Great card! It let's you use the monsters from your grave, plus it provides fodder for Network. Chimeratech Overdragon says hi
I feel like having monsters on your field is the key to the deck. Now, you might say it's for every deck, but here more than any other. Take Mermails, there the key is a lot of hand cards. Or Chaos Dragons, having a well-filled grave. That's why I put in some protection like Honest, Solemn, Bottomless, etc.
I'll prefer having 1~2 Maxx "c" than putting 1~2 veiler on the main
I might try that. It's just Veiler gives some more protection, and it is needed in this deck.
