Default mode beaten. Next is Hardcore mode.
The team used is a rain team with Pelipper as the centerpiece. I was a little worried I had no physical offense, but it wasn't a problem.
Gengar @ Choice Specs/Focus Sash depending on fight
Gengar is a ghost type which is basically useful for switching into Close Combats (and Earthquakes with Levitate). It can be good with Gengarite, but I used Charizard for mega in pretty much all fights. Choice Specs makes for hard-hitting Shadow Balls and Sludge Waves on the switch-in. Chandelure is a better alternative though with higher special attack and very useful ghost/fire typing. Hypnosis is very good though.
Ability: Levitate
Timid Nature
- Sludge Bomb
- Dream Eater
- Shadow Ball
- Hypnosis
Zapdos @ Choice Specs/Assault Vest/Choice Scarf
Zapdos was was surprisingly useless in the Elite Four. It was brought along for the rain team, but electric wasn't that useful. It was good vs Lorelei though. Scarf is probably the best item for Zapdos. Maybe another defensive wall would have been better such as Walrein with Fur Coat or defensive Milotic.
Ability: Pressure
Timid Nature
- Hurricane
- Weather Ball
- Thunder
- Roost
Chansey @ Eviolite
Chansey is basically cheating as it can switch into ghost types (though I didn't bring any moves to hit those with Chansey), set up Stealth Rocks and Toxic and tank special attackers indefinitely.
Ability: Natural Cure
Calm Nature
- Seismic Toss
- Toxic
- Soft-Boiled
- Stealth Rock
Pelipper @ Damp Rock
Pelipper is the MVP of the team along Ludicolo. Sets up the crucial rain, awesome moveset with useable special attack and tanks physical hits very well. I'm not sure how I'm gonna beat hardcore mode without abusing weather haha.
Ability: Drizzle
Bold Nature
- Hurricane
- Protect
- Scald
- Roost/Ice Beam
Ludicolo @ Leftovers/Assault Vest
Ludicolo is the offensive MVP of the rain team. Extremely useful typing both offensively and defensively, beefy especially with Assault Vest and excellent movepool. Swift Swim even allows for Modest nature. Fake Out is mandatory for breaking Focus Sash and Multiscale.
Ability: Swift Swim
Modest Nature
- Giga Drain
- Icebeam
- Scald
- Fake Out
Charizard-Mega-Y @ Charizardite Y
Charizard-Mega-Y has huge upfront special power attacks and very good coverage. It brings even more weather control and counters some things the rain team doesn't handle well like steel types. Lorelei's rain team was destroyed by Charizard-Mega-Y together with Ludicolo and Pelipper.
Ability: Drought
Timid Nature
- Flamethrower
- Roost
- Solar Beam
- Focus Blast
Honorable mentions:
Lanturn. Very good typing.
Tyranitar. Even more weather control. Beffy as fuck in sand + rock typing in Sandstorm + Assault Vest.
Excadrill. Physical sweeper when coupled with Tyranitar because of Sand Rush.
Slowbro. Slowbro is just the best Pokemon ever.
Scizor. Hits hard with priority Bullet Punch + Choice Band.
Noivern. Invaluable for farming ressources with Frisk + Thief (nuggets, mushrooms, heart scales and more).
