hello, i have some months of ORAS competitive battle. however, i have found some pretty interesting techniques using certain pokemon. to begin with, this team isnt centered in a mega evolution pokemon. so this mega pokemon can vary depending on your preferences.
#1 jirachi
evs: 252 HP
176 SpD
80 Spe
item
choice scarf
moveset
trick
iron head
ice punch
u-turn
jirachi can get help by pokemon like focus sash leafeon. using swords dance to baton pass and choosing jirachi can lead to some sweeps using iron head with a 60% chance of flinching due to jirachis serene grace. choice scarf makes jirachi be faster than most pokemon, however it locks jirachi to one move. so choose wisely. unless you do trick, trick can force pokemon that usually have status moves like swords dance, manaphys tail glow, etc to use only that move. forcing them to switch while you gain momentum. but this makes jirachi slower making its sweeps harder
#2 meloetta (piruette based)
evs 252 Atk
252 Spe
item leftovers/focus band
moveset
relic song
psychic
close combat
calm mind
one of the most hard to use or most occasional pokemon in this set is meloetta. like always it starts in its aria form. you can prepare some calm minds and proceed to use relic song. once meloetta has done this you can change between its piruette form to its aria form if you need it. or use close combat against bulky Sp Def pokemon. you can also use a life orb but it will most likely kill meloetta easily due to other pokemon attacks and its not so good defense. once meloetta did some calm minds it will be hard to kill while leftovers recover it.
#3 leafeon
evs 252 atk
252 speed
item
focus sash
moveset
swords dance
leaf blade
knock off
baton pass
leafeon is a vital part of this team, working as a support for jirachi. using swords dance and then baton pass to jirachi can make a small sweep. leafeon also works to handle threats like bulky calm mind slowbro and, if you opponent chooses a fire type pokemon you can always do knock off, dealing a good amount of damage if it doesnt kill (obviously after some sword dances)
#4 manaphy
evs 4 SpD
252 Sp Atk
252 Spe
item
leftovers
moveset
toxic
surf/hydro pump
tail glow
rain dance
manaphy is a really strong pokemon in this set. 2 tail glows maximize your sp atk. also despite manaphys slow look it can be really fast with a 100 base Speed stat along with ev training makes him faster. manaphy can handle treats like blissey by just doing rain dance and tail glow. healing itself with hydration from typical blisseys with toxic. this pokemon has a great sweeping potential
#5 serperior
evs 252 sp atk
252 speed
ability
contrary
item
life orb
moveset
leaf storm
giga drain
leech seed
hidden power fire/ice
serperior is one of the best sweepers in this team. contrary makes leaf storm sharply raise his special attack. also serperior has a really high base speed plus the ev training. so being slower isnt something to worry about. leaf storm hits really hard and gets stronger each turn. when serperior HP is low due to life orb giga drain comes to action.
mega gardevoir
evs
252 Sp Atk
252 Spe
item
gardevoirite
moveset
destiny bond
moonblast
psychic
calm mind
mega gardevoir can get really bulky after some calm minds. also it makes it stronger. it can handle dragon types easily with its moonblast. while doing destiny bond if you predict you opponent will KO you. misuse of destiny bond can lead other pokemon to make their stats stronger while if you fail to predict you waste valuable turns
