Do you think it's good or bad?
I ran across this quote in the Redemption topic. Here it is and below is my answer.
When have net deckers ever contritbuted to a playing community? They don't.
Actually, my playgroup wouldn't be as good as it is now if it wasn't for net decking.
Net decking is very good for an environment. Sure, you hear the rapid complaints of "You sir, have no originality!" or "YOU'RE A NETDECKER AND NOTHING ELSE!!!" but let's talk realistically. A winning deck gets posted online. You build that deck, whether it's card for card or loose construct, take it back to your store, and proceed to stomp face. Sure, your group is pissed, but here is where the netdecker takes control. Instead of stomping face week after week, encourage your players to build decks to compete with it.
When you bring a winning deck to your store that is higher than your store's caliber, you are bringing in the best to your playgroup. That top deck makes nearly every other deck better. Why? Because players learn how to tech. They will run cards to counter other decks. They will revise their deck and replace cards that didn't help them with cards that will help them.
When this game first started in Feb/Mar 2006, my playgroup started playing, but didn't really rocket into the competitive meta until July 2006. Why is this? We all played jank until I went online and copied TemplarPsi's Phoenix Championship Zasalamel deck. I proceeded to stomp everybody in the store. I got the usual dirty remarks, but I didn't care. I encouraged my playgroup to tweak their decks to beat it. Lo and behold,everyone and their mom increased their tempo to keep up with it, balanced out their play to keep up with it, and teched against it. After that, we didn't even need to netdeck that much as we were acustomed to competitive play. We knew what was good and what was not.
They called me a netdecker over three years ago. I don't care. We've been in the big boyz crew ever since because of netdecking.
