>Tournaments: Treasures of the Sands

I'm in favor of the card-based option. Regarding the semi-finals, why send the heroes to the organizer in advance? It seems a bit unfair; whoever gets lucky and correctly guesses the anti-heroes wins. Wouldn't it be better to have a regular semi-final? Player 1 chooses a hero, Player 2 chooses an arena and a hero, and then they switch. Also, why are there 5 games in the final? 5 games in the semi-finals and 5 games in the final? Wouldn't it be better to have 7 games?
