I think that is posible to do a Cup facing the best assos of each country, using 1 or 2 seasons to develop a interesting tournament that should have a final round with the best 4.

If the last week for example we play the "final four", so we do it in one season of 4 weeks, the round before would need 16 assos, the 2nd 64 and the 1st 256.

So only the winner go to next round in my suggestion, 3 eliminated.

I really would do it representing mostly of countries maybe in a proportion of associations created and always without chance to manipulate the draws so taking into account the contry that everyone has choosen when started the asso.

:P
