Fake Tears Whimsicott

Landorus-Therian (M) @ Sitrus Berry
Ability: Intimidate
EVs: 4 HP / 252 Atk / 252 Spe
Jolly Nature
- Earthquake
- Rock Slide
- Protect
- Imprison

Imprison Landorus is an idea shamelessly stolen from /u/sqishyrina. Max Speed to help check for Scarf on other Landorus. Is a neat idea but I rarely even brought it to a match.

Gengar @ Gengarite
Ability: Levitate
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
- Shadow Ball
- Sludge Bomb
- Dazzling Gleam
- Protect

The Mega of the team. Hits hard and fast. Dazzling Gleam helps get around redirection as well as hitting Hydreigon and dealing good damage to other dragons, pairs really well with Whimsicott.

Whimsicott @ Focus Sash
Ability: Prankster
EVs: 28 HP / 4 Def / 252 SpA / 4 SpD / 220 Spe
Timid Nature
- Encore
- Taunt
- Fake Tears
- Moonblast

Honestly probably the star of my team. Encore is deadly, Taunt prevents lots of opposing shenanigans. Fake Tears makes Gengar even more deadly, as well as boosting damage for Blaziken and Thundurus. Moonblast for damage and in case of getting hit by Taunt. The Speed is faster than max Speed Thundurus with max SpA since bulk is a little silly with Sash. The extra EVs are however put in a way to maximize general bulk for help with weak hits and increasing longevity just a little.

Blaziken @ Life Orb
Ability: Speed Boost
Level: 50
EVs: 4 HP / 64 Atk / 196 SpA / 244 Spe
Naive Nature
- Hidden Power [Ice]
- Overheat
- Protect
- Low Kick

Mixed attacker is the best use of Blaziken. Outspeeds adamant Landorus, meaning one speed boost beats most scarf variants. OHKOs Kanga, Terrakion, Heatran, Bisharp, Amoonguss, Aegislash, Salamence, and Landorus with various super effective moves. Very strong against huge chunks of the meta.

Thundurus-Therian @ Choice Scarf
Ability: Volt Absorb
Level: 50
EVs: 76 HP / 252 SpA / 180 Spe
Timid Nature
IVs: 0 Atk / 30 Def
- Thunderbolt
- Hidden Power
- Grass Knot
- Psychic

Faster than Jolly Landorus because otherwise I wouldn't have an idea for what to be faster than. Extra EVs in HP. Psychic improves the match up against Mega Venusaur and Grass Knot nails Terrakion and the water types that are immune to Thunderbolt, curse you Gastrodon!

Talonflame @ Sharp Beak
Ability: Gale Wings
EVs: 4 HP / 252 Atk / 252 Spe
Adamant Nature
- Will-O-Wisp
- Brave Bird
- Protect
- Quick Guard

Quick Guard helps protect this super fast team from priority. Namely other Brave Birds and Kangaskhan Sucker Punch. Will-O-Wisp is cool for crippling physical attackers. Brave Bird is Brave Bird.
