"Emolga's flight speed, Tynamo's lightning, and the Pokémon she hasn't sent out yet... presumably, both the first two and the last are speed-oriented." Dian adjusted his glasses. "That's precisely what makes this move worth using."
He swiftly hurled the Poké Ball in his hand. "Slowpoke, Trick Room!"
"Now, let thy speed become my strength!"
Ideally, he would activate Trick Room only after scouting all his opponent's Pokémon. Otherwise, if she sent out a Pokémon slower than his own, he would be digging his own grave.
However, very few Pokémon were slower than Slowpoke. The chances that Elesa's final ace was a Shuckle, Munchlax, or something similar were extremely low.
"So you did bring a Pokémon that knows Trick Room." Elesa watched the blue barrier envelop the entire field without the slightest change in expression. As a Gym Leader who specialized in speed, she naturally understood room-based tactics very well. "Come back, Tynamo."
She raised her hand, preparing to switch Pokémon.
"Block." Dian's lips curled upward. "Consider this payback for earlier!"
Slowpoke flicked its tail. A red light abruptly appeared around Tynamo, forming a question-mark-shaped symbol before vanishing in a flash.
Under Trick Room's influence, Slowpoke executed its move almost as swiftly as Tynamo's lightning earlier. There was no way to dodge!
"A textbook Trick Room strategy." Elesa watched the recall beam return empty-handed and put away her Poké Ball, knowing Tynamo was in danger.
"Trick Room reverses speed, and Block prevents the target from escaping." Brock's expression was grave. "Mr. Yingyue really is experienced."
"It's over." Dian showed neither joy nor sorrow. "Slowpoke, Zen Headbutt."
Before he had finished speaking, Slowpoke suddenly appeared right in front of Tynamo. A violent surge of Psychic power erupted, engulfing it...
BOOM!!
Tynamo blasted straight through the barrier and slammed into the arena wall
