And then there is the other 80% of the time. It's full of name calling, and taunting, and uncreative strategies like blade stacking or spamming. It gets so frustrating that I find myself yelling insults at the screen that I wouldn't use if that person was playing me at chess or some other strategy based game. I also felt really so down after being beaten by blade stackers a few times in a row that I considered going out and grabbing a bunch of treasure card blades or only playing on my Myth wizard with a TON of earthquakes. But then I thought to myself, "No". Because that's not how I want to play the game. What I enjoy isn't just winning, it's playing a good match.
I also enjoy good sportsmanship. Which unfortunately is why I tend to keep my mouth closed most of the time. I also don't say "GG" every game, because often it isn't true. If you're calling me a noob or you're spamming me or blade stacking, or just being really obnoxious it wasn't a good game. I understand that saying "good game" is a polite gesture, but a polite gesture becomes an empty gesture when it has no meaning.
I encourage everyone to try PvP and to try new strategies. Find some friends to do it with you. Go to someone's house. Get a theme (but holidays are already taken, so sorry ^_~). Play with a odd assortment of schools. Say "this couldn't possibly work!" then go ahead and try anyways. Go for the original, not just the sure fire, because then you'll appreciate the true satisfaction of playing and winning.
Good luck, and may the force be with you.
