why does everyone have 2 use the same style of deck like: wind-ups, chaos, inzektors, mermail, & sam's. i know that u can post up ur decks her but does that mean 2 make the deck & keep it. i thought the deck creator was made 2 make a dec that u think will turn out good & it'll b an orginal.
just asking so please don't take it the wrong way every1

I'm not sure I understand what your saying...... If u mean on ADA then we hardly ever post those decks but if ur talking about the entire YGO community then I'm afraid those people are unoriginal noobs

Probably because they use DN as main dueling engine?!. Craving for exp and rating makes to use the easiest way to go up. (for online dueling)
Another reason are tournaments. I never played in a tournament or even if I done that, I lost my interest in the tournament. Others, on the other hand, participate in them and all want they want is wining - and here is the part where meta kicks.
As for real life, you need to invest money in your decks, and you would pay some extra for a better product.
And one more thing: I hate when my opponent knows he's wining (duh..empty field) and they swarming, swarming, swarming, swarming...you got the point.

Tournaments, so top tier decks are used, and all decks are original, the only thing is, would be that one would take the original deck, and copy it. All decks are made by a certain group of people, but later divided to others.
Also, to your other proposal about the deck construction. It is used to make a deck, that you would like original, or maybe not original, but to also have help from others in what to add or take out to make it that much better.

Point done.

wow ask 1 question & get a different responses from different dueliest

@geo yup, cause no one is the same, n everyone have their own point of view,
anyway, one big issue is that plp play irl too, n so it costs money, so they tend to buy cards/decks that do very well, n so they rely on top teirs in order to make use of their spent money + to c if their Irl deck works good, they go to DN n test their top tier deck n c how well they go,
Another group of plp just play top tier in DN in order to get high ratings n be on the so called *top 200 players*, some friends ik value that very much... so yeah
