End Ordovician (Gengar) @ Choice Scarf
Ability: Cursed Body
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
- Shadow Ball
- Sludge Wave
- Focus Blast
- Dazzling Gleam
Named after the oldest mass extinction out of the "Big Six" that saw the extinction of 45-60% of marine genera and 85% of marine species, Gengar makes up a revenge killer core with Dragapult and was this team's original inspiration. With Choice Scarf as well as speed EV's and Timid, Gengar focuses more on a naturally high special attack to take down threats that shut down sweeps or to deal with potential dark type sweepers that are immune to Prankster. Sludge Bomb was initially played with in place of Sludge Wave for the extra poison chance but it really wasn't worth the 5 less BP, in my opinion.
End Devonian (Corsola-Galar) @ Eviolite
Ability: Cursed Body
EVs: 252 HP / 252 Def / 4 SpD
Bold Nature
- Will-O-Wisp
- Strength Sap
- Stealth Rock
- Night Shade
The primary hazard setter and a wall in the later game, Corsola is named after the Late Devonian Extinction (also known as the Kellwasser Event) which made 19% of all animal families and around 50% of all animal generas extinct. Corsola was a later addition to the team, replacing Runerigus. I chose Corsola over Runerigus for a bit more defense with Eviolite and Strength Sap at the cost of Toxic Spikes which I think is fine trade given that Corsola already passes around statuses with Will-O-Wisp. Night Shade serves as a way to deal sizable damage (around 20%) to Pokémon that would otherwise resist Ghost such as Grimmsnarl.
End Permian (Aegislash) (M) @ Weakness Policy
Ability: Stance Change
Shiny: Yes
EVs: 252 HP / 252 Atk / 4 SpD
Adamant Nature
- Swords Dance
- Shadow Sneak
- Brick Break
- Iron Head
Named after the "Great Dying" -- the largest recorded mass extinction event -- Aegislash serves as a great setup sweeper with an attack stat reaching a maximum of over 1,000. Shadow Sneak covers faster Ghost types and possible threats such as Metagross and Tapu Fini. Brick Break deals with the screens that may be set up by Ninetales-Alola or Victini. Iron Head is used to cover fairy types that Gengar either can't deal with due to being KO'd or not wanting to lose the stat boosts from Swords Dance and the Weakness Policy.
End Triassic (Sableye) @ Leftovers
Ability: Prankster
EVs: 252 HP / 4 Def / 252 SpD
Careful Nature
- Taunt
- Will-O-Wisp
- Knock Off
- Recover
Named after the extinction event that secured the dominance of dinosaurs on Earth for 65 million years, Sableye shuts down setup sweepers with Prankster and Taunt as well as Will-O-Wisp to hurt the attack stat. Knock Off gets rid of potentially threatening items such as the Choice family or Weakness Policies and Recover is used to make sure that Sableye can stay in the fight long enough to clear the field of these threats. In all honesty, Sableye is probably the weakest link of the group; by the time a setup sweeper comes out I'm usually busy with a revenge killer to send Sableye out in time to stop at least part of the setup on mons such as Alakazam.
End Cretaceous (Dragapult) @ Choice Specs
Ability: Infiltrator
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Shadow Ball
- Draco Meteor
- Flamethrower
- Thunderbolt
Dragapult makes up part of the revenge killer core with Gengar and is named after the mass extinction that saw the end of the dinosaurs and rise of mammals. Choice Specs add onto Dragapult's already decent Special Attack while Timid and 252 EV's in Speed give him a whopping 421 Speed. Infiltrator is chosen to take care of substitute Pokémon such as certain Zapdos sets. Flamethrower has been chosen over Fire Blast for better accuracy, which can potentially win battles. Also, the Pokémon named after the death of the dinosaurs has Draco Meteor. That's funny.
End Holocene (Polteageist) @ White Herb
Ability: Weak Armor
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Shell Smash
- Shadow Ball
- Stored Power
- Giga Drain
Named after the current ongoing mass extinction due to human influence on Earth, Polteageist is a late game setup sweeper forming a loose core with Aegislash. Shell Smash combined with White Herb adds bonuses to Polteageist's already good Special Attack and Speed. Giga Drain allows Polteageist to stay in the fight for as long as he needs, Shadow Ball takes care of pesky Ghost and Psychic types, and Stored Power has a whopping 140 BP when used alongside Shell Smash, giving Polteageist an incredibly hard-hitting STAB move.
