Pokémon Rejuvenation - Zetta 5 (Electric/Ground Dual Type)

Difficulty: 6/10
Zetta's last major fight has him bringing his A game, with many fast and hard hitters like his Typhlosion (that has caused me so much grief over the course of this playthrough), Weavile, and Absol. Luckily, his AI kinda freaks out seeing Krookidile and just... explodes? I'm not quite sure why he does this.
Chapter 15 Electric types:
Aevian Lampent (Evolve Aevian Litwick: Axis Factory, if not Mystery Egg)
Chapter 15 Ground types:
None this chapter.
Rules:
I can only use Electric- or Ground-type Pokémon in battle. I can have non-Electric- or Ground-type Pokémon on my team, but they can't contribute to the battle in any way.
I'm also not allowing myself to use Pokémon that eventually evolve into Electric- or Ground-types, but aren't Electric- or Ground-types themselves (For example, Mudkip would be disallowed, but Marshtomp wouldn't be)
I can't use two of the same Pokémon.
I can't use items in battle.
The whole run is being done on Normal mode. I'm not insane enough to put myself through Intense mode, sorry.
