Pablo: I'm sorry you got the short end of the stick, but I personally can live with a system that fails under such unlikely conditions. I'm sure many others can too.
Also, and perhaps more to the point, you seem to want a system that finds and rewards skill and skill alone. Firstly, how in the world do you propose that happens? How are you supposed to measure pure skill in any way? You simply can't, and if that's your main concern, then you could complain about any and all possible systems. Unless I'm overlooking something, so if you have any ideas, please share. Second, what's with this skill obsession anyway? Do worlds matches have this magical property where all luck is eliminated and it's a pure skill event? No, it's just like any other game of pokemon! Luck is constantly a part of any game, even the most elite ones, so it doesn't really even make sense to try and purge luck from the equation. Luck is rewarded in this game; always has been, and barring major card design and rule changes, it always will. Live with it or don't; your choice.
