"Light Screen!" Tachi conjured a mirrored shield that weakened the Shadow Ball's attack before it struck. The Future Sight that Tachi saw earlier struck the Sylveon.
"Trick Room!" Tachi was blasted, but the Espeon survived the attack thanks to the defense boosts from Calm Mind. Tachi used her psychic powers to create a zone of twisted dimensions encompassing the whole battlefield.
"Shadow Ball!" With the Trick Room in effect, Tachi was able to out-speed the Mega Alakazam. The Espeon conjured an orb of shadow energy and launched it at Sherlock.
