A wild trailer appears, featuring Z-moves for Solgaleo, Lunala and Necrozma!

[HeroLinik]

Those names of the new Z-moves though...they're a bit of a mouthful. Also, there's some stuff about the previously revealed thing about Rotom being an actual use and letting you reuse Z-moves, and O-Powers are sorta returning as well through Rotom as well! Thoughts?

O-Power are basically back through Rotom Powers, REJOICE!

Aside from the double Z-Move one everyone?s talking about, there?s also one for hatching and EXP (YUSSSSSSSS), among others.

Seems like a version of O-Powers are back again! That's great news :O

 

[Pyrax]

As convenient as Roto Loto seems for breeding and grinding, I'd rather have DexNav again. But hey, at least Rotom Dex is actually useful outside the plot and dex. :p

 

[Hikamaru]

Great to see O-Powers are back. Definitely makes me want to keep playing US/UM more than S/M.

Anyways, here's the Japanese trailer as well:

O-powers are back, which is cool. Something tells me the 2 Z Moves per battle would be limited to in-game only. Exp. and hatching O-powers were the ones I used most in Gen VI and those would ease grinding and hatching eggs in US/UM.

Anyway, the thought of offensive Stealth Rock Dusk Mane Necrozma is starting to sound scarier the more I imagine it, as it has a nuke in Searing Sunraze Smash and Photon Geyser as a stronger Psychic STAB than Zen Headbutt:
-Stealth Rock
-Photon Geyser
-Sunsteel Strike
-Earthquake
Nature: Adamant/Jolly
EVs: 252 Atk/4 SDef/252 Spe
Item: Solganium Z

Calm Mind Lunala would appreciate its personal Z Crystal over the Ghostium Z in order to still bypass defensive abilities unlike Never-Ending Nightmare:
-Calm Mind
-Psyshock/Hypnosis
-Moongeist Beam
-Focus Blast
Nature: Timid/Modest
EVs: 4 HP/252 SAtk/252 Spe
Item: Lunalium Z/Psychium Z (latter for Z-Hypnosis for +1 Speed)

Dawn Wings Necrozma can also pull off the above, minus Z-Hypnosis, as well as Photon Geyser as a possible Psychic STAB. Lack of Shadow Shield would hurt, though.

Definitely helps to have Exp power back. Training should be easier. I can't wait to test out the new z moves.
