(to anyone who sees that post, nevermind it, i just saw the recent post) so basically rotom gains access to rock, fire, water, poison, grass, ground (immunities via abilities don't count), bug (bring on the heal order/ quiverdance rotom W), fighting, ghost, dark, ice, it gets so many options. def a top tier threat that can easily suprise its opposition. seriously, it can run so many things.
shaymin gets new rock attacks, not too much really but still something. stealth rock is nice to have.
castform gets rock, ground, electric, and water moves...nothing really noteworthy...
darmanitan actually gets a fair bit, at first i was going to shrug it off. but then i remembered, it gets dark moves. so thats something. other then that, it gets ghost...meh.
wormadam gets...flying, bug, water, ice, rock and fire interchangably which is cool. it can probably run a nice quiver dance set or something, nothing too overwhelming.
melo can run flying, psychic, fighting and fairy moves. all pretty good additions.
and hoopa u gets dark and ghost. void/quiverdance anyone?
