Pikachu starts against Spiritomb. Volt Tackle teals a ton of damage, but because of the big recoil damage from it, Spiritomb should be bulky enough to live a hit and revenge-ko it considering it has good defences and attack
Red will then likely send Snorlax, which is immune to ghost attacks and has good special defenses and will able able to KO Spiritomb
Cynthia in returns sends Lucario, whose typing walls anything Snorlax throw at it and KO it.
Red sends Charizard in, which can KO Lucario with its fire moves
Cynthia will send Gastrodon, which can easily tank Charizard's attacks and KO it in return with water or rock moves since it has Stone Edge.
Red will send Venusaur who can easily KO Gastrodon will 4 times effective Grass moves
Cynthia will send Roserade, which resist most of Venusaur's moves and has super effective Extrasenssory to overpower it
Red will send Lapras to defeat Roserade, but because it doesn't outspeed, it takes a lot of damage from super effective grass moves before being KO-ed by Blizzard
Cynthia will send Milotic next, which can wall the Lapras and defeat it with its moves and heal damage off with Aqua Ring
Red will be down to his last Pokémon left, Blastoise, who can likely score a win against Milotic, but due to Milotic's typing and defenses, this won't be easy for it, especially if it'd have to rely on low accurcy Focus Blast to do substancial damage
This will wear down Blastoise as Cynthia sends in her final Pokémon, Garchomp. Because Blastoise will be weakened from the fight against Milotic, this will leave it in a position for Garchomp to finish off Blastoise with Earthquake or Dragon Rush, concluding the match with Cynthia as the winner
