The Semi-Final Frontier!

Ash has defeated Paul and advanced to the semi-finals of the Sinnoh League. Ash's biggest challenge, however, is now ahead of him. His next opponent is Tobias, who has won his eight badges and advanced to the semi-finals of the tournament using solely his Darkrai. Will Ash be able to defeat Darkrai, as well as Tobias's other Pokémon, and advance to the finals?
