After the conclusion of the DE ladder, there will be one undefeated team in the Top Bracket (the Champions) and one team with exactly one defeat in the Bottom Bracket (the Challengers). These two teams will meet in the Grand Final, which will consist of 7 games. The winner of the Grand Final is the team that accumulates the most points in the 7 games of the match. If both teams accumulate the same number of points, the team that won more individual games in the match is the winner. If there is still a tie, the teams will play a single tiebreaker game to determine the winner of the match.

If the Grand Final is won by the Champions, they will have proven themselves the undisputed champion of the tournament and will be awarded the 1999 Myth World Cup. However, if the Challengers win the match then both teams will have one defeat on their record and the match will proceed to the Sudden Death Final, a series of games to be played immediately after the Grand Final.

In the Sudden Death Final, each team will alternately choose a game/map combination to be played, with the Champions choosing the first game. Any game/map combination that has been played in prior rounds of MWC99 may be selected, but once a map or a game has been selected in the Sudden Death Final it cannot be selected a second time by that same team. The first team to win two consecutive games is declared the winner and will be awarded the 1999 Myth World Cup.

If neither team has won two consecutive games after ten games have been played in the Sudden Death Final, the Triumvirate will select a single game as the Ultimate Sudden Death game. The winner of this single game will be awarded the 1999 Myth World Cup.

An example Sudden Death Final series might be:

• Champions pick Desert Stampede, 14 minutes
• Champions win.
• Challengers pick Clash Flag Rally, 10 minutes
• Challengers win.
• Champions pick Untamed Lands Flag Rally (2v2 Allies), 10 minutes
• Champions win.
• Challengers pick Trow Body Count, 10 minutes
• Challengers win.
• Champions pick Lichen Captures, 14 minutes
• Challengers win.
