LV gongrats on your cloned shinys. BTW cloning ios just sharind the wealth people although I wouldn't share my 1/80800 sumthing luck but oh well.
So your team needs improoved moves and EV training. To re-ev train is very VERY hard because you need rare special berries to do so. So too bad if you didn't.
As for shinys their natures are almost allways bad(exept of course my golden adamant spearow untrainedXD )
Latias @ souldew EV train for speed and sp.attack and mabe deff
thunder
solarbeam
psychic/dragonclaw/icebeam
recover/calm mind
You can make it work with either or goudon/kyogre
jirachi @ leftovers or shell bell ev for HP and sp.attk
wish/rest
thunder
doomdesire/cosmic power/ calm mind
psychic
Good for long lasting battles even works for DP I think, but for DP replace doom desire w/ that steel type beam thing cuz it's still special attk based
lugia @ leftovers or shell bell
substitute
recover/rest
aeroblast/psychic/psichoboost(psycho from pokemon XD) for the sake of attk
toxic
makes a good staller plus you already have them other two tanks so its perfect for a half staller team I even beat 3 pokemon(latios, rayquaza and latias) with that moveset even though I didn't have substitute lol!
Rayquaza @ quick claw/choiseband/focusband EV att and speed
dragondance
earthquake
arial ace/hp flying/fly or rockslide/aiciend power/hp rock
hyperbeam
really the black sheep but can get you out of a sticky situation whan someone uses sunnyday on kyogre
or EV sp.attk and speed @ quck claw/ focusband/ choiseband
thunder/thunderbolt
flamethrower
icebeam/dragonclaw
surf/hypebeam(come on you HAVE to use it's great attak!)
works great because thunderbolt is powerfull against icebeamers wich are part water, flame thrower cannot be weakend by weather and defeats them hearty steel types, surf won't be lowerd either! Either ice beam or dragon claw, DC for STAB power or Ibeam for those pesky little salamences and flygons that almost all dragontrainers have. Hyperbeam cuz if you are facing a chansey you'll get your butt kiked with toxic and softboiled unless you have attak. I'll have to study a little more to give you a good DP moveset but here's a prevew for atack: dragon claw,earthquake, arial ace, dragon dance.
The Sp. attack one is WAY too complicated to remember so I'll tell you later.
Groudon @ quick claw/ left overs/ focus band
Overheat
aicientpower/hyperbeam/bickbreak
earthquake
swords dance
The dreaded bad ability goudon wich I love BTW. OK so Overheat is weak but it gains power from drought and it will take over half of an opponent groudons HP and hoping youre the faster one you will win,
Earthquake has STAB and it's so efing powerfull it will rock your socks if used with the right partner. Aincient pwr and those will just fill a gap and all suck inDP but in that case you can teach it firepunch instead of overheat and thunderpunch instead of the other fillers. WOW its gonna be good in DP, well good enough. Swords dance if used corectly with earthquake and them punches in DP or aincient power/hyperbeam in colosseum will defeat almost ANYTHING with one blow cuz of groudon's terific and terrorizing attk and drought=fire punch DP
KYOGER @ leftovers/shellbell/ that one awaikening berry EV SP. attk and speed/deff
rest/calm mind
icebeam or hyperbeamDP/ calm mind
surf/waterspout
thunder
Oh dear kioger, so versitile and powerfull yes it is an 00ber that's up there with mewtwo. Well rest and that blasted berry will get you out of sticky situations with a little luck if used after a few CMs a task better done by suicune but oh well. Ice beam will take care of most grass types unless they survive and pull off sunnyday then youre doomed with chlorophil and solarbeam. Surf gains both STAB AND DRIZZLE power making it 90x1.5 x1.5=202.5!!!!! Damn straight! Or a full HP water spout would be 150*1.5*1.5=337.5 WOW!!! But you must keep in mind that waterspout will get wore as your HP decreases so iot might not be a good idea.
And to state the obvious thunder gets 100% accuracy plus kyogre's big ol' sp.attk stat.
As you can see this can be a potentially dreaded by all team unless the opponent has a slaking and a better strategy or you don't EV train.
I hope I helped lol!
