So,i'm not good in NU but i have a made a team in that tier.Hope its good.
EV's:4 Def / 252 SpA / 252 Spe
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.
EV's:252 HP / 252 Atk / 4 SpD
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.
EV's:EVs: 252 HP / 252 Atk / 4 Def
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.
EV's:4 HP / 252 Atk / 252 Spe
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.
EV's:32 HP / 252 SpA / 224 Spe
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.
EV's:4 HP / 252 SpA / 252 Spe
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.
