I have been running a Cyber-Stein Deck and its been doing pretty good, but I want to see if I'm missing anything that needs to be in there. Here's the list:

MONSTERS:

3x Cyber Stein
2x Steamroid
1x D. D. Warrior Lady
1x Sangan
1x Jinzo
1x Blowback Dragon
1x Magician of Faith
1x Tsukuyomi
1x Breaker the Magical Warrior
1x Exiled Force
1x Cyber Jar
1x Morphing Jar
1x Cyber Dragon

SPELLS:

3x Megamorph
2x Giant Trunade
1x Dark Hole
1x Limiter Removal
2x Creature Swap
1x Scapegoat
1x Snatch Steal
1x Brain Control
1x United We Stand
1x Heavy Storm
1x Mystical Space Typhoon
1x Swords of Revealing Light
1x Mage Power (Will replace with Lightning Vortex once I get it...)
1x Book of Moon
2x Enemy Controller

TRAPS:

1x Torrential Tribute
2x Phoenix Wing Wind Blast
1x Call of the Haunted

FUSIONS:
3x Master of Oz
1x Cyber Twin Dragon (I know that I need more...)
0x Cyber End Dragon (I need some!)
1x Thousand Eyes Restrict
... and many more...

I think this is how my deck goes, but I'm only doing this from memory. Anyway, the objective of this deck is to take out the opponent swiftly with Cyber Stein's fusion monster(s) and win in one turn, or an OTK. However, I threw in other cards in case I cannot summon the fusion beasts. So, help me out if you can. ^_^

Cyber Power: mechanized defenders of the universe is my deck that I did months ago it's in my signature.

basicly it's focused around machine duplication technique and cyber dragons.
It's ok though it's a catchy name one that I actually stole off of a old robot toy called cyber power. But then it's kind of a homage.

on to your deck:
don't forget that megamorph as clever as it is can act to boost your own attack or drain a opponents attack. (equip megamorph on a opponents monster while your life points are higher

-1 megamorph
-2 steamroid
-1 cyber stein
-2 phoenix wing wind blast
-1 united we stand
-1 brain control
-1 mage power
-1 creature swap

+2 smashing ground
+2 drilloid
+2 sakuretsu armor
+1 7 tools of the bandit
+2 mystic wok

mystic wok is a easy common that is here for 2 reasons: 1 a megamorphed or especially a limitered machine gets very big so you can convert it into life points before it backfires. (megamorph or limiter backfire) and then with cyber stein you pay 5000 life points. and then cyber end dragon attacks!! sakuretsu armor? chain your face down mystic wok. and kill your cyber end to gain 4000 or more life (IF you megamorph you gain 8000.)

That way. you can summon huge monsters by paying life points and hold mystic face down to absorb the huge monsters when their about to be destroyed. since wok is quick play you can use it on spell speed 2 or lower destruction effects in the chain. (sakuretsu armor=2 dark hole=1)

This deck could use some more polish but it has the makings of a competitive archtype. 8.5 /10.0 after changes.

go check out my old deck cyber power and if you want. But I'd prefer it if you'd rate my xyzvw deck cannons core.

It sounds pretty decent, but wouldn't Trap Jammer be better in this situation? After all, there are hardly any traps in the game that are not used competitively outside of battle (except Call of the Haunted and Waboku/ Threatening Roar)? In addition, I intend to run one or two more Cyber Dragons and possibly even Power Bond. Having two ways for Cyber Twin/End Dragon out onto the field is my goal, while also being able to continue fighting when I lack the supplies (such as a bad hand or Cyber Stein w/out Megamorph, etc.).
Also, I just made up Cyber Power off the top of my head, sorry.
Any other opinions, though?

Summoner of Illusions is one of the most under-rated cards in the game. You put 2 of those in there and it'll be a lot better. You should only need those powerful fusions for one turn and they'll do the trick without costing you 5000 big ones.

You must remember, though, that 5000 life points is actually a GOOD thing. That's right, a good thing. Megamorph feeds off this and doubles my fusion's attack power for the game.

You could always throw in Gyroid and use Power Bond.

That also sounds like a good idea. After all, I might as heck since I will be running Power Bond (later). The power of machines are rising again!!!
