That one time I was able to beat a 'good' chess player at school :-) I still remember that one. Usually I lost, but... I also came to the chess club rather to play Magic: the Gathering, so I didn't mind.

With that in mind, it has been a while (more than twenty five years) but what you said sums up the one time I went to my first Magic: The Gathering tournament, by having to build a deck with a limited amount of packs. You don't have the advantage of owning any power cards there (unless if you are lucky). What happened? Well, you could see who was doing well based on where they sat. And, I got absolutely wrecked! But, I also had a very bad (useless) rare [Shauku, Endbringer]. Which I shouldn't even have put in my deck, but I still did, cause.. it was a rare! [1] Still, there's much more luck to be had with decent commons and uncommons. In later tournaments (different types), I did better, and my fav experience (apart from some of my cards being stolen on a later tournament at that location) was the one where you'd buy a bunch of packs, open a pack up, and pass the packs on. Some people would pick only meta cards, some people would only pick expensive ones, others would always pick rare ones. If you don't intend to win, that could be a decent strategy. But I went for the strategy where I would pick the best cards for my deck, and that worked out well.
