I used to play magic with my friends when I was in school and we made the mistake of actually going to the game shop and trying to play with people there. We all got demolished by the tryhard dudes there because we just made decks with cards we thought were cool and they all knew the meta gaming stuff. On top of that they were assholes about it. We never tried that again.

I did manage to win one game with a combo I had that allowed me to generate an infinite number of 1/1 tokens but that was sheer luck.
