The most dangerous moves for that edition were single target so a redirector was needed. Amoonguss was the best one since it knew both Spore and Rage Powder, and everyone was prepared against powder, sandstorm damage and grass overall with either using MVenusaur or just using Safety Googles.
Sejun main attackers were MGyarados and Talonflame, both weak against Electric attacks, Garchomp could patch up a little the Rock Weakness, but not the other.
Pachirisu was the only "bulky" user of Follow Me that year, the others two were Furret (No redeeming qualities) and Lucario (used as an offensive Pokémon). Having access to Nuzzle (Untauntable Thunder Wave and Sash Breaker), Super Fang and Follow Me with Volt Absorb meant that Pachirisu will nullify almost every Volt Switch and Thunderbolt so his Gyarados and Talonflame were free to dish damage.
Pachirisu was the definition of a right call of the metagame.
