After Shirona’s surprise choice of Daimaxing her Togekiss, Satoshi activates Lucario’s mega evolution. In a fierce battle where Togekiss refuses to give in, Lucario manages to take it down. Shirona brings Gaburias back out as her final Pokémon. To close out the battle, Shirona calls for a Dragon Claw, while Satoshi commands Lucario to use Reversal. Both Pokémon take the hit from their opponent, but Lucario is able to pull through. Satoshi officially defeats Shirona and moves on to the final round to face Dande. (Source: Wikipedia)
