A fun fact is that from experience, Icy Wind can normally KO Dragonite after rocks damage. Meaning that Icy Wind can KO all of those annoying 4X weakness to Ice pokemon. Meaning you can use that instead of HP Ice and scrap Calm Mind for HP Electric on Keldeo-R. I would also run Life Orb, because from my experience, it's much better ( Also that fact was w/ Life orb. ). Just make sure you have your rocks up before trying anything, on D-nites, lol. Forretress could use a Red Card. Charge Beam works better on Alakazam than Substitute ( For when you're blind hitting something switching in or you're finishing off something with really low HP ) and Psyshock is a bit better than Psychic. Latias looks good. Terrakion also looks good. For Dragonite Dragon Claw is much more reliable, and when you're tacking in boosts before hand, you can afford reliability. Switch Jolly nature for Adamant.
Dragon Claw > Outrage. Adamant > Jolly.
Is good. Although, I think a classic Wishpass Blissey may be more beneficial to your team. ( [email protected]

The " Red Card " item works amazingly on Forretress. I would try that > Leftovers personally.
Icy Wind instead of HP Ice which lets you run HP Electric instead of Calm Mind.
Psyshock > Psychic and Charge Beam > Substitute.
