Suggestions on alternative Pokémon are Gengar and Scizor.
Gengar has access to Taunt and Levitate. That mean he can 6-0 Kyla and completely shut down Eduard’s lead.
Szicor is just SOO GOOD! With this set:
Scizor @ Metal Coat
EVs: 130 Hp / 252 Atk / 128 Spe
Scizor still underspeed London’s Mega Reunicluss, resist his Focus Blast and setup a Swords Dance and then destroy his team barring Jellicent. He also wreak havoc to Yuki.
