Mamanbou
Base Stats:
165/75/80/40/45/65
Okay so it's offensive stats aren't very pretty, but it's defensive capabilities are definitely something to talk about.
Abilities:
Hydration: When Rain Dance is in effect, this Pokémon heals itself of burn, freeze, paralysis, poison, and sleep at the end of each turn. If rain ends on the same turn that this Pokemon is afflicted with a status, that status will not be healed.
Healing Heart: Will occasionally heal teammate's status problems (?)
Regeneration (Dream World): This ability heals 1/3rd of this pokemons HP when switching out.
Hydration and Regeneration are both great abilities for Mamanbou. Hydration gives it 1-turn 100% healing with Rest, which is amazing considering this thing could have nearly as much defensive potential as suicune. Regeneration will aid it in Wish Passing, and lets it worry more about healing it's teammates than itself.

Wish: Something that sets Mamanbou apart from many of the other water types. Regeneration also lets it heal itself when it switched out, so it's definitely possible to Mamanbou to keep supporting its team throughout the match.

Mirror Coat: Mamanbou is likely an above-average user of Mirror Coat thanks to its amazing HP stat. While it won't be reflecting Thunderbolts any time soon, it still has enough HP to take lots of neutral special attacks and reflect them back. Thanks to 165 base HP, it'll take a huge chunk out of the opponent, and you can heal afterward with Wish, Rest (and Hydration), or Regeneration.
TM
TM04 - Calm Mind, TM06 - Toxic, TM07 - Hail, TM10 - Hidden Power, TM13 - Ice Beam, TM14 - Blizzard, TM16 - Light Screen, TM17 - Protect, TM18 - Rain Dance, TM20 - Safeguard, TM21 - Frustration, TM27 - Return, TM29 - Psychic, TM30 - Shadow Ball, TM32 - Double Team, TM42 - Facade, TM44 - Rest, TM45 - Attract, TM48 - Troll, TM55 - Boiling Water, TM77 - Psych Up, TM87 - Swagger, TM90 - Substitute, HM03 - Surf, HM05 - Waterfall, HM06 - Dive
Calm Mind: Calm Mind could help it's pitiful Special Defense, but it won't really be hurting anything with it's special attack anytime soon.
Boiling Water: Mamanbou really shouldn't be using it for the damage, more for the burn chance which would help with Mamanbou's already impressive Defense.
Potential Sets
Mamanbou is definitely a supporting pokemon. I could see it with something like:
Mamanbou w/ Regeneration/Hydration
Impish, Leftovers
252 Def / 252 SpDef / 4 Spe
-Wish
-Protect
-Light Screen
-Boiling Water
Mamanbou would be useful paired with something like Zapdos, who could heal off the SR damage with Wish, and take the incoming Thunderbolt to get a Special Attack Boost.
How do you think Mamanbou will fair in what seems to be a very offensive metagame so far? Will its wish-passing capabilities make it stand out, or is it only a worse Vaporeon/Suicune?
