I taught Louise the move Rock Tomb, replacing Force Palm.
"Louise, use Rock Tomb!" Louise roared, bringing down enormous rocks. Sylveon dodged left and right, weaving around them as nimbly as a leopard.
Sylveon charged in with Double-Edge, but Lucario was a Steel-type, so Normal-type attacks weren't very effective against him.
"Here it comes! Grab Sylveon!" Lucario carried out my command perfectly and immediately used Brick Break on Sylveon! Sylveon broke free at the last moment, turning the attack into a glancing blow that did only a little damage. Unexpectedly, Sylveon closed in again, and a wave of Moonlight Power struck Lucario head-on. Lucario dropped to one knee. It looked like he was almost out of stamina!
I had to get him to finish this quickly! "Lucario, trap Sylveon with a tight formation of Rock Tomb!" Lucario aimed at the spot where Sylveon would land and formed a ring of rocks. Sylveon landed right inside it!
"Go after it! Put all your strength into Brick Break!" Lucario's face twisted fiercely as he charged forward like a mad beast. Below him, Sylveon gritted its teeth and used Psyshock to fight back. Lucario leaped from side to side among the rocks, dodging the beams, then used gravity to bring a vicious chop down on Sylveon! The prison formed by Rock Tomb fell apart, sending dust flying. Lucario crouched on the ground. Sylveon lay collapsed.
I leaned close to Meimo's ear. "You can throw it now." Meimo threw her Poké Ball, which shook three or four times before going still. Princess Ali happily ran over to Meimo. "What a pretty Pokémon! Sis, I want to see it too."
Wutong stopped them. "Let's give this Sylveon a little rest first!" As expected of a Champion's son, he really knew how to care for Pokémon!
