The World Coronation Series battle between Satoshi and Dracaena begins with Satoshi starting off with Negigaknight, while Dracaena brings out her Onvern. After Negigaknight struggles, Satoshi swaps it for Uonoragon. Dracaena also switches Onvern in favor of Tyltalis, which becomes Mega Tyltalis moments later. Uonoragon isn't able to do much, so Satoshi brings Negigaknight back out. Negigaknight takes out Mega Tyltalis with a Meteor Assault, but it faints as well. Onvern and Uonoragon are brought back out. The two Pokémon clash with Dragon Pulse and Dragon Rush, with Onvern fainting from the hard hit. Satoshi earns himself another victory and rises to 9th overall in the standings. (Source: Wikipedia)
