Net decking

Net decking is taking a deck posted on the Internet and playing it, with little to no modification.

Some gaming purists look down upon it because it removes the deck building aspect from the card game. The flip side is that building effective decks is challenging and time consuming and the more players and games a deck goes through, the more the play style and its contents are refined, making it even more effective, and thus more desirable to copy, thereby creating a virtuous cycle.

Is net decking bad?
That depends on who you ask, everyone has their own opinion on the matter, some people are against it, some are neutral and some encourage it, either way just play however you want, no one can stop you.
