There is always a supporting cast and a main one. Example: Vampire genesis, Crush Card Virus/Vampire lord, Ryu Koki, Summoned skull, Giant Germ. (from my plague deck...awesome!!!) killer, i won in 2 turns with it once.
Well, the minimum in a yugioh deck is 40 cards maximum 80cards. Most people try to have a smaller deck over a larger deck, to get cards they need. About a 40-50 card deck is good.
cuz he's better
A good and cheap Yu-Gi-Oh deck that you can make for under 70 bucks is the Samurai deck.
It can be a good deck. you just need the cards to go with it. Like you need Quilbolt hedgehog, hes a good card to go with a synchron deck. also junk, Nitro, Road, Turbo, Quick, and hyper Synchrons. and then you need cards that help bring them out.
Get a structure deck, any structure deck. Then, buy the 500 card lot from amazon.com and start getting rid of junk cards, like Normal Monsters in your deck. Find the cards that go with your deck, and add those cards. Swap some cards. But keep your deck at 40. If not, DO NOT go past 45 cards. There will be a smaller chance that you draw the card you need.Link to 500 card lot:http://www.amazon.com/YuGiOh-Trading-Cards-Premium-Rares/dp/B002R8IU4Q/ref=sr_1_9?ie=UTF8&qid=1289053469&sr=8-9
the wickeds (avatar,dreadroot) dark armed D. and red dragon archfiend
the three gadget and magnet or you could get the yusai fudos cards. like junk syncron and them.
I would then suggest a normal monster strike deck. This deck uses normal moster and equip spell cards with other spell and trap cards to boost your monster strength. It has cards like "Sword of the Soul-Eater", "Sogen", and "Collected Power".
its good! you just need some cards to modify it!
There is no such thing as an unbeatable deck. However, some decks are better than others. You just have to keep improving. Good luck
You could ask friends who live near you who also collect yugioh about the deck but other than that it's up yo you to use good cards to help you make your zombie deck
I run a very good dragon deck and the only equip card I run is Axe of Despair. 1000 attack.
