the best Yu-Gi-Oh deck you can build is one that goes with your playing style.
there is no deck better than the rest but if you know how to properly use a well built deck, you should have few problems with dueling. if your into powerful cards that overwhelm the opponent i would suggest an old fashioned machine deck with perfect machine king in it. if you want a deck that is well rounded and has strong monsters, i suggest a monarch deck. if you want to be really sneaky and rely on strategy and well thought tactics, you should use crystal beasts or a DD. deck with the 3 helios cards. hope this helps :)
Get the warriors triumph structure deck and improve from there.

The best deck for this card would most likely be a beast or an EARTH deck.
Its free (but you have to download), LackeyCCG and Byond (Duel Monsters Genesis).
The best Yu-gi-oh player is Yugi because he started and has the best deck!
The best deck to stop kagemaru is one that does damage to him when he use's any of the three decks.

Go to yugioh-card.com to learn the rules. You can also get a rulebook in each structure deck and a "beginner's guide" in each starter deck.
no, but there is a yugo ap for the i phone where YOU make your own deck, or you can go to the deck doctor and you give him your deck and he will fix it up for you, or if you have a friend that is an absolute pro like me :), you can ask of him to help you with your deck.
chaos is using the best light and dark monsters and making a deck (include Black luster soldier-envoy of the beginning and chaos sorcerer) and twilight is a lightsworn build that uses some dark support like chaos sorcerer, necro dardna, tragodia, gorz, and DAD
