"What is netdecking?" you might ask. Well, netdecking is when you don't want to go through the pain of trial and error in deck construction for a card game, so you go online and look up some of the best decks. Then you recreate them!
I'm talking about Hearthstone at the moment, but netdecking applies to any card game with deck building.
Since I've been trying to get back into ranked play I'm finding myself needing to netdeck to get anywhere at all. This game used to be newbie friendly, even in ranked play, but it's not as much anymore. Once you get to rank 20 or less (lower numbers are better in Hearthstone) the opponents start to get really good and if you don't have a modern deck with good cards you don't stand much of a chance.
I used to be able to get really far in the ranked mode, even with the standard starter decks. I can't imagine what it must be like for someone who is completely new to the game picking it up right now. With the expansions and solo adventure cards there are a ton of cards out there to make great decks. Starting out must be extra difficult these days.
