So,i'm not good in NU but i have a made a team in that tier.Hope its good.
Charizard@Leftovers
Ability:Solar Power
Nature:Timid
EV's:4 Def / 252 SpA / 252 Spe
-Sunny Day
-Fire Blast
-Solarbeam
-Air Slash
This guy is my favourite! Sunny day is the strongest in the set which charizard can have with solar power.Fire blast as stab,power gets increased by sunny day.Solarbeam to cover some of charizard's weaknesses and becomes a one turn move in the sun.Air slash as stab and can make the target flinch if i am lucky.
Machoke@Eviolite
Ability:No Guard
Nature:Adamant
EV's:252 HP / 252 Atk / 4 SpD
-Dynamic Punch
-Payback
-Rest
-Sleep talk
Dynamic punch is the best stab machoke could get with perfect accuracy.Payback gets double power since machoke is slow.Rest combined with sleep talk makes it a perfect combination.
Seismitoad@Leftovers
Ability:Poison touch
Nature:Adamant
EV's:EVs: 252 HP / 252 Atk / 4 Def
-Earthquake
-Drain Punch
-Protect
-Aqua Ring
This set is fun to use as i have used this effectively.This is more of a healing set.Earthquake a stab move and has great power.Drain Punch for some healing.Aqua ring for more healing.Protect for protecting yourself and you can heal some Hp from aqua ring and leftovers.
Ursaring@Toxic Orb
Ability:Guts
Nature:Adamant
EV's:4 HP / 252 Atk / 252 Spe
-Facade
-Close Combat
-Crunch
-Sword Dance
This set wrecks Havoc! Facade is the main stab and gets powered up by guts.Close combat for extra coverage.Crunch to take care of those ghost types and swords dance for an attack boost.
Vanilluxe@Leftovers
Ability:Weak Armor
Nature:Modest
EV's:32 HP / 252 SpA / 224 Spe
-Flash Cannon
-Ice Beam
-HP Fighting
-Autotomize
I have used this set effectively and it has been good.Autotomize boost vanilluxes' speed. Flash cannon for coverage against rock types. Ice Beam as stab and HP fighting for more coverage.
Electabuzz@Eviolite
Ability:Static
Nature:Timid
EV's:4 HP / 252 SpA / 252 Spe
-Thunder Bolt
-Volt switch
-HP Ice
-Focus Blast
Thunderbolt is your primary STAB move for electabuzz.Volt Switch is good to have, as early-game Electabuzz does a solid job at forcing switches.Hp ice for coverage agaist ground types.Focus Blast is a good move to have for coverage.
So yeah,hope you like it.
