Gyarados-Mega @ Gyaradosite
Ability: Mold Breaker
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Waterfall
- Dragon Dance
- Earthquake
- Substitute
Mega Gyarados is the main Pokémon on this team. The goal is to set up on Pokémon that fear Mega Gyarados such as Heatran, Gliscor and Landorus that are locked into Earthquake. Water fall is the main spam, use it mostly at all times. Dragon Dance is the typical set up move for most Pokémon. Substitute is so you can set up on Pokémon like Gliscor and Chansey when they use toxic. And Earthquake is another good move for spamming. This helps Mega Gyarados have better coverage and hit Pokémon that normally wall it out such as Tapu Fini, Rotom Wash, Toxapex and Ferrothorn.
Ferrothorn @ Leftovers
Ability: Iron Barbs
EVs: 252 HP / 4 Atk / 252 SpD
Sassy Nature
IVs: 0 Spe
- Power Whip
- Gyro Ball
- Protect
- Leech Seed
Ferrothorn is a important Pokémon to preserve when fighting a rain team. Power whip is for Greninja and Swampert, these two Pokémon aren’t really big threats but do hurt some of the team. Gyro ball is a excellent stab move that allows Ferrothorn to hit many fast Pokémon very very hard such as Tapu LeLe, Latias/Latios and Mega Alakazam. Leech seed is because Ferrothorn always has leech seed. And because it allows it to hurt Pokémon that might switch into it. Protect is a great move for scouting out what the opponent might do as well as stopping Pokémon that have high jump kick.
Landorus-Therian @ Flyinium Z
Ability: Intimidate
EVs: 252 HP / 112 Def / 144 Spe
Impish Nature
- Stealth Rock
- Earthquake
- Fly
- U-turn
Landorus Therian is a useful Pokémon for many teams. The goal of Lando is a bluffing scarf lead. Greninja is a big problem for it so leading with Landorus against a team with Greninja is not a option. Thankfully Ferrothorn and Tapu fini can deal with that. Earthquake is the main stab move that doesn’t really need much explanation. Fly is the Z move that allows Landorus to hit every grass type in the tier very hard. Stealth rocks is for setting up on Pokémon that fear or can’t hit Landorus. Other Landorus that are locked into Earthquake and Tapu KoKo. U-Turn is so you can have a free switch on Pokémon that might switch on you after rocks are up. And U-Turn can be used to hit Pokémon that can’t OHKO you and cause problems like Tangrowth and Serperior that want to set up a substitute.
Tapu Fini @ Leftovers
Ability: Misty Surge
EVs: 248 HP / 16 Def / 12 SpA / 40 SpD / 192 Spe
Calm Nature
- Defog
- Moonblast
- Scald
- Taunt
Tapu Fini is a helpful Pokémon that aids Mega Gyarados with misty terrain. Mega Gyarados getting burned or paralyzed is a big problem. So having misty terrain is very useful. Tapu Fini also helps with occasional stall. Scald is the main stab move that hits Heatran and Victini pretty hard. Moonblast is the second stab move that hits Greninja and most other Pokémon relativity hard. Taunt is so Pokémon can’t set up Spikes or rocks and so Toxapex can’t spam toxic spikes in your face. Defog is for defoging.... This will allow you to get rid of any hazards that may be a problem. Stealth rocks take a big chunk of Gyarados health. So defog is very useful for Gyarados and even Gengar is some cases. Bringing in Tapu Fini on Greninja and Toxapex is a great way of dealing damage and getting rid of any annoying hazards that might be on the field already.
Greninja-Ash (M) @ Choice Specs
Ability: Battle Bond
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
- Surf
- Dark Pulse
- Spikes
- Water Shuriken
Ash-Greninja is a great Pokémon that helps deal over all damage to allow Gyarados to sweep. Both Greninja and Gengar aid eacthother dealing damage very quickly. I chose surf over hydro pump just because of sheer miss chance. Surf is the main stab move that Greninja will be using a lot. Spikes is for setting up on Pokémon that will definitely switch out scared of Greninja. Heatran, Victini, Gliscor, Blacphalon and Iron head locked Jirachi will always switch(unless the opponent wants to sacrifice one of these mons) so using spikes can deal little chip damage and can weaken non bulky Pokémon Like Mega Alakazam. Dark pulse is the other main stab move that is used for obvious water type switch ins like Toxapex and Swampert. Water shuriken is for priority and for picking of weak Pokémon that may out speed Greninja.
Gengar @ Choice Scarf
Ability: Cursed Body
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Shadow Ball
- Focus Blast
- Sludge Wave
- Energy Ball
Gengar (paired with Greninja) also has the role of dealing damage and clearing the way for Mega Gyarados. Shadow ball hits many Pokémon in the tier like Mega Latias/Latios and Blacephalon. Sludge wave is another good move that hits many Pokémon very hard and can be a real Tapu killer. Focus Blast is so Mega/Normal Tyranitar doesn’t pursuit trap you and for Ferrothorn. Energy ball is so you have a 100% accurate move that hits Ash Greninja, Quagsire, Mega/Normal Swampert and Gastrodon.
