I've actually got a reverse of the stories posted. Kinda. Its sorta related anyway.
So, I was at a Dark Ascension tourny thing, a few weeks ago and I just play casually, like really casually generally with some friends and a friend asked if I wanted to come, so I agreed. I knew the game, just didn't have a huge store of cards, he said the buy in got you six packs to make a deck out of and everyones was gonna be shitty, I said awesome and agreed.
The games are going great and I am having a great time. I've seen a few guys who are like Hardcore into this game like this guy who is cool and chill before but the second he sits down he doesn't say a word. And it kinda throws me cause I am just tryna be a nice guy throughout.
Towards the end, I get paired against this kid who is really good. He has a good deck that is pretty well thoughtout, he drafted well. And he wins the first game, and we are on the second. About halfway through the second game I have a Vorapede with three +1/+1 counters on it, a pretty terrifying sight, but he kills it and I am like 'Well..damn in that case I will attack you with..an Undying Wolf! Muwahaha" and he cracks a smile. First emotion I have really seen all game.
After the game he comes up to me, he won, and he says "I gotta give it to you, you kept things fun, even while you were losing, I wish more people would"
