| Mirages of Mismagius II/VS. Mismagius II
Fantina's Mismagius has already defeated Platinum's Empoleon and Ponyta with Trick Room. The only Pokémon left is Diamond's Lax, who is surprisingly under the effect of Mismagius's Trick Room, to which Fantina replies gleefully that she studied them all, thus, Mismagius's attack fills the room with food, much to Platinum's despair.
Lax starts eating happily, until he spots three Berries floating around, and tries to eat them; Pearl tries to warn Lax that it was in fact Mismagius, but too late, since it uses Energy Ball and lands a direct hit. Pearl then asks Diamond what they should do, before noticing a carefree Diamond eating and drinking as well.
The situation is getting out of control, Platinum can't think straight, and Lax is merrily eating (as well as Diamond). Pearl realizes that they underestimated their opponent, as they had plenty of tactics planned down for this match, but Mismagius's attack took them down at once. Diamond suddenly starts running away, trying to get some cups of noodles, but falls into a hole (even though Pearl tried to stop him), but he doesn't feel any pain at all. Pearl then says that he's lucky because it's an illusion, yet Diamond enjoys it the same; and suddenly discovers something.
Pearl checks Mismagius's entry in the Pokédex, on which it says that some chants bring happiness. Even if it's the same illusion, everyone reacts to it differently, Platinum and Pearl having a headache, because they both have a strong sense of reality, unlike Diamond and Lax, who aren't suffering at all. Pearl rushes back to the battle field, where Platinum still looks worried about Lax and the possibility of him getting tired out. Fantina then tells Mismagius to finish it off...
Pearl tries to get Platinum's attention with a huge ice cream cone and a donut, eating them in front of her; he and Chatler then use the seesaw, trying to make Platinum realize that it's best not to fight back against the illusion, to make her enjoy it along with Lax.
Much to Pearl's joy, Platinum starts eating with Lax, bonding with him again; Fantina looks displeased at Platinum's lack of seriousness and commands her to fight her again, then tells Mismagius to use Energy Ball again, but a heavy ball (previously thrown upwards by Platinum and Lax), falls knocking it out, and thus, winning the match and making the illusion fade away as well.
Fantina asks if that move was Fling, and checks the ball as well, being an Iron Ball, the item that does the most damage. Pearl then proceeds to explain how they got it (it was found at Celestic Town, after all of those metal items were dug out of them); and Platinum says that she wanted to use Lax's Dark-type move since she was going to fight against a Ghost-type Leader, and even if Iron Ball slowed Lax's speed, she followed Pearl's advice to use it since Diamond's Pokémon aren't very fast to begin with. Pearl then adds that they got unexpected help, since Trick Room would swap the order of the Pokémon (the faster being the last one to attack), thus, making Lax's Iron Ball to hit first.
Fantina then awards Platinum the Relic Badge, congratulating them for defeating her Mismagius's Trick Room, as nobody had defeated her in years, even if Pearl gave Platinum bits of information, making it unfair, as stated by the Sinnoh Chairman; Fantina replies that they were under the same attack as well, and they couldn't give proper advice under said effects.
Platinum thanks Fantina and she replies saying that she loves both smart and interesting kids, encouraging them to study hard and play hard. Then she remembers about Diamond and asks for his location. They rush into the hole Diamond fell into a while ago and ask him if he's okay; he's a bit dizzy, but he says Poké-ay (with Poké Balls in his eyes). This makes everyone laugh.
Fantina then tells them about the Canalave Library and that they should go there. Fantina says that there's an Academic Conference being held at the moment in there, as she heads with them to watch the television. But the news say something strange. The Pokémon Research Team is missing...
