Made a few edits.
Dragapult @ Heavy-Duty Boots
Ability: Infiltrator
Tera Type: Dragon
EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- Dragon Darts
- Dragon Dance
- U-turn
- Phantom Force
The lead attacker. Dragon Dance makes the guy deadly, and almost nothing moves before him with his amazing speed. Dragon Darts is quite powerful, being a 2-hitting move that can get past Focus Sashes. Phantom Force is for brute force that can be used for finishing opponents quick. Also, opponents cannot run from it, because it bypasses protection! Be aware of Normal types, though. When all else fails, use U-Turn and get out of here.
Glimmora @ Focus Sash
Ability: Toxic Debris
Tera Type: Rock
EVs: 252 HP / 4 Atk / 252 Spe
Jolly Nature
- Spikes
- Stealth Rock
- Toxic Spikes
- Mortal Spin
Everyone's favorite hazard setter. If you see a pokemon that you know learns Rapid Spin / Defog, switch to Gholdengo, For Gholdengo is...
Gholdengo @ Expert Belt
Ability: Good as Gold
Tera Type: Fairy
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Make It Rain
- Nasty Plot
- Shadow Ball
- Dazzling Gleam
... An offensive Spin Blocker. Defog fails, and Rapid Spin / Mortal Spin don't affect him. But, he has very good offensive capabilities, usually on slower opponents. Make It Rain is a very powerful STAB move, at the cost of your Sp. Atk. However, after a Nasty Plot, you can use 2 boosted MiR's. Shadow Ball is also STAB, and Tera Fairy + Dazzling Gleam makes for giving Dark types a rather nasty surprise.
Garganacl @ Leftovers
Ability: Purifying Salt
Shiny: Yes
Tera Type: Fighting
EVs: 252 HP / 4 Def / 252 SpD
Careful Nature
- Salt Cure
- Iron Defense
- Recover
- Body Press
Garganacl has some of the best bulk around. Physical attackers can barely harm him. Salt Cure gives passive damage, and you can Recover while the opponent wears away. Iron Defense is this guy's Sword's Dance, because it powers up Body Press. Tera Fighting turns boosted BP into a nuke.
Deoxys-Speed @ Red Card
Ability: Pressure
Tera Type: Dark
EVs: 248 HP / 8 Def / 252 Spe
Timid Nature
- Psychic Noise
- Taunt
- Thunder Wave
- Knock Off
Speed control has arrived. This guy is super annoying. He can stop you from healing (cough cough Gliscor coughcough) with Psychic Noise, he can Taunt pokemon relying on setup or hazards, he removes items with Knock Off, and can give your team some Speed Control with Thunder Wave. Red Card forces out those who actually want to hit him. Tera Dark is for defensive purposes. Honestly... sometimes I lead with Deo instead of Glimmora.
Iron Crown @ Booster Energy
Ability: Quark Drive
Tera Type: Steel
EVs: 252 SpA / 4 SpD / 252 Spe
Modest Nature
IVs: 0 Atk
- Tachyon Cutter
- Agility
- Psychic
- Volt Switch
I've had problems with Magic Guard Clefable, so I replaced Alomomola, who wasn't very useful anyway. Tachyon Cutter is basically D-Darts with infinite accuracy. Agility speeds Iron Crown up, and turns him into a reliale sweeper after Quark Drive boosts his Sp. Atk. Psychic is STAB, and Volt Switch is for getting out of the way of steel types.
