Hi! I'm kinda new to Pokemon battling but I have tested this team out and tried my best to edit it but I'm still having some problems.
Weavile: Lead
Nature: Jolly (+speed/-sp.atk)
Item: Focus Sash
Ability: Pressure
EVs: 252 Spd/126 Atk/126 def./4 HP
Moves:
As a lead pokemon, I use Weavile primarily for taunt for the annoying entry hazard leads or occasional trick room team. Its 3 other attacks give exceptional coverage for the types of the common leads (like Tyranitar, Azelf, Hippo). If it can't 2HKO the lead Pokemon, I usually switch it out since it's my only real physical attacker. It's biggest problem is a lead with a fighting attack, such as Machamp. Fighting is the main weakness here.
Togekiss
Nature: Timid (+spd/-atk.)
Item: Lum Berry
Ability: Serene Grace
EVs: 252 Spd/252 Hp
Moves:
I usually switch in Togekiss against weak fighting/grass types. They usually switch out and I use Nasty Plot. The biggest problem with Togekiss is the luck factor using Air Slash, making it unreliable. Togekiss is also unreliable when the opponent is faster than it, but using a choice scarf loses my access to Nasty Plot, which makes Togekiss substantially weaker. It is used for any Pokemon that I do not have a better choice to counter with, hoping that Air Slash flinching can defeat a Pokemon that would otherwise give me trouble. Sometimes Togekiss does very well, and sometimes it just fails.
I have also tried using baton pass instead of roost, and passing it to Jolteon who has a much higher speed. It doesn't always work and is pretty risky.
Tangrowth
Nature: Brave (+atk/-spd)
Item: Leftovers
Ability: Chlorophyll
Evs: 252 sp.def/ 128 HP/ 128 def.
Moves:
Tangrowth is primarily my defense wall, and a good switch in when I'm predicting an EQ or another physical attack that Tangrowth can easily resist. I usually start off with sleep powder just in case the opponent switches. EQ and Seed Bomb gives good coverage for the water/ground and fire types since I have barely any other moves to counter those. It can usually tank one fire STAB hit from most Pokemon that aren't boosted or have a high atk./sp.atk, and EQ usually KOs them or do around 80%. Then, I switch in to another Pokemon, such as Vaporeon, or Extreme Speed Arcanine, to KO it.
Arcanine
Nature: Modest (-atk, +sp.atk)
Items: Leftovers
Ability: Flash fire
EVs: 252 sp.atk/128 def/128 sp. def
Moves:
Arcanine is probably the one that needs the most work. I know that Arcanine is more of an attacker than a special attacker, but its physical moves usually cause too much recoil damage. Its physical moves also has a smaller movepool, so this gives Arcanine more coverage. His ability allows me to absorb fire attacks, which is when I usually switch him in. Dragon Pulse is to surprise any Dragon types that come in and don't expect it. It does a nice amount of damage, so if Arcanine faints then another Pokemon can quickly take it down. HP Electric for the predicted water type. Overall, Arcanine is not too reliable. It might be better to just replace it overall, so suggestions are appreciated.
Vaporeon
Nature: Calm (-atk./+sp. def)
Items: Leftovers
Ability: Water Absorb
EVs: 252 HP/128 sp.atk/128 sp. def
Moves:
Vaporeon comes in on a predicted water attack. It is a nice sp. def wall, and a decent water-type. Toxic is for anything that it can't do a decent amount of damage to or if I'm predicting a switch, and ice beam is just for better coverage.
I am considering switching this with a Starmie, since none of my other Pokemon know any Water attacks, and this one is too slow. Starmie's Psychic can also be beneficial against a fighting type. But, it's obviously more frail, which could hurt my team's defenses.
Jolteon
Nature: Timid (-atk/+spd)
Item: Choice Specs
Ability: Volt Absorb
EVs: 252 Sp.atk/252 spd/ 4 HP
Moves:
Jolteon is actually one of more reliable Pokemon. It comes in on against a lightning attack. Its choice specs allow it to 2HKO most Pokemon with Thunderbolt that are not particularly specially defensive or resist it. HP Ice is really my only counter to ground/flying types, since Vaporeon's Ice Beam is usually too slow and easily predicted so the opponent switches out. Yawn is there to scare off any Pokemon that seem like trouble, but with Choice Specs it also forces me to switch out.
Note: I prefer not to use any pseudo-legendaries/legendaries. I hate them and refuse to use any :[
Threat List:
There are probably many, but the ones that give me the most trouble are:
Heatran - He has been pretty problematic since most of my Pokemon with the right super effective moves are too slow/have a type disadvantage to get an upper edge.
Blissey - If Weavile is fainted, I have a hard time countering Blissey.
Breloom - Spore is evil...
Kingdra - My only hopes are Arcanine with Dragon Pulse and Jolteon, but Arcanine can only attack if the opponent switches to Kingdra while Arcanine is still out. If Kingdra gets too many DDs, then Jolteon is obsolete. It usually comes with a Lum Berry, so I can't toxic/yawn it or else it gets a free DD.
