Hey this is the first team I've had a good win streak with, but I can't consistently get wins. I'm wondering if you guys have any tips on tweaking my team for more consistency.
Drapion
Item: Leftovers
Ability: Battle Armour
Nature: Careful
Moveset:
Toxic Spikes
Whirlwind
Crunch
Earthquake
EV's: 252 HP, 4 Def, 252 SpD
I'm using Drapion mostly just to lay down Toxic Spikes, but Drapion is infact a great baton pass chain breaker, due to whirlwind. I find Drapion really effective because of it's bulk, but it doesn't have many other strengths apart from Toxic Spikes, Whirlwind, and bulk.
Conkeldurr
Item: Leftovers
Ability: Guts
Nature: Brave
Moveset:
Bulk Up
Drain Punch
Mach Punch
Stone Edge
EV's: 120 HP, 252 Atk, 136 SpD
I used to use Lucario, but he wasn't really an effective asset to my team, he was easily killed by any pokemon with Earthquake. Now that I have Conkeldurr on my team I can easily KO pokemon after using Bulk up, and if I use it more than once the opponent almost has no chance of breaking down my Conkeldurr, of course a strong special attacking pokemon could destroy my Conkeldurr, but my team is now a lot more stable.
Metagross
Item: Air Balloon
Ability: Clear Body
Nature: Jolly
Moveset:
Agility
Meteor Mash
Earthquake
ThunderPunch
EV's: 52 Hp, 252 Atk, 204 Spe
Metagross is my physical bulk, and my second physical attacker. Not much to say about Metagross, it's been doing fairly well, maybe a few things I need to change to make Metagross a more effective attacker, but I've been doing alright defending with Metagross, I just need to watch out for ground type moves.
Latios
Item: Choice Specs
Ability: Levitate
Nature: Timid
Moveset:
Outrage
Surf
Ice Beam
Shadow Ball
EV's: 252 SpA, 4 SpD, 252 Spe
I switched Gengar with Latios, I am now finding it a lot easier to counter other dragons, and with such a versitile moveset I can use him to KO other pokemon. Latios>Gengar because of better all round stats, and all round stats. I can counter many pokemon with Latios, and out speed many, I don't get KO'd as easily as with Gengar.
Umbreon
Item: Leftovers
Ability: Synchronize
Nature: Careful
Moveset:
Wish
Payback
Heal Bell
Protect
EV's: 252 HP, 4 Def, 252 SpD
I would almost not consider changing a thing about my Umbreon, it's working perfectly. Part of the reason Umbreon is so successful is Drapion's Toxic Spikes. Umbreon has not only been amazing for resisting special attacks, but also physical attacks. I have definitely used Umbreon to it's maximum potential.
Item: Life Orb
Ability: Levitate
Nature: Timid
Moveset:
Psychic
Flamethrower
Nasty Plot
Grass Knot
EV's: 252 SpA, 4 SpD, 252 Spe
I changed Mew with Azelf, Azelf's speed helps me utilize the varieties of special attacks, and with Nasty plot it Azelf becomes a really threatening special attacker.
I am aware that my team has some flaws like; most players with a ground pokemon could devastate my team, and to counter those pokemon I would need at least one grass type move, but I'm not sure where to incorporate it.
Anyway please leave some suggestions, anything will be muchly appreciated.
(Edited) Replaced Lucario with Conkeldurr. Replaced Gengar with Latios. Replaced Mew with Azelf.
