Name: Rankurusu
Type: Psychic
Ability: Magic Guard or Regeneration
Base Stats: 110 HP, 75 Defense, 125 Special Attack, 85 Special Defense, 30 Speed
Type: Psychic
Notable Moves: Calm Mind, Recover, Pain Split, Reflect, Light Screen, Toxic, Thunder Wave, Trick, Trick Room, Psycho Shock, Focus Blast, Shadow Ball, Grass Knot
Notes: Magic Guard is an incredible ability that makes Rankurusu immune to entry hazards, status (besides sleep), weather, and so on. He may be able to abuse Flame Orb with Trick with Magic Guard--if Flame Orb is even available in this generation. While Magic Guard is difficult to pass up, Regeneration is an interesting alternative that heals 1/3 health whenever the the user switches out. Rankurusu has a lot of great support options, but might also make a potent bulky attacker, with Calm Mind, Recover, and Psycho Shock at his disposal.
Name: Musharna
Type: Psychic
Ability: Synchronize
Base Stats: 116 HP, 85 Defense, 107 Special Attack, 95 Special Defense, 29 Speed
Notable Moves: Rest, Sleep Talk, Moonlight, Calm Mind, Reflect, Light Screen, Baton Pass, Substitute, Barrier, Toxic, Thunder Wave, Yawn, Hypnosis, Trick Room, Psycho Shock, Shadow Ball, Charge Beam
Notes: Sleep Talk is no longer a TM in Black/White--Musharna is one of the only new pokemon lucky enough to learn Sleep Talk as an egg move and have the bulk to make use of it effectively. Synchronize, along with Rest/Sleep Talk, will make Musharna a good status absorber. Rest/Sleep Talk/Calm Mind or Charge Beam might be a good place to start. He also learns Baton Pass, and can pass Calm Mind and 101+ Substitutes.
Name: Barujina
Type: Dark/Flying
Ability: Dustproof
Base Stats: 110 HP, 105 Defense, 95 Special Defense, 80 Speed
Notable Moves: Roost, Knock Off, Whirlwind, Toxic, Taunt, Mean Look, Nasty Plot, Air Slash, Dark Pulse
Notes: His attack stats and move pool are lacking, but Barujina has good typing and defenses all around. Roost/Whirl Wind/Knock Off/Taunt or something could imitate Skarmory, but I'm not sure if there would be any point in using Barujina over him. He's more specially defensive, but with a lack of good support moves, no steel typing, and pitiful offensive stats, he might just be inferior.
