Mesprit, the most balanced of the Sinnoh Trio. It can boltbeam and has a decent enough movepool to do well. The question is, what is it that it can do that others can't? Cresselia has the levitating wall thing down (poor Uxie ._.), Azelf has the fast sweeping thing down, and really the only thing that Mesprit has over those two is a more balanced stat allocation and a true boltbeam. 80 base speed means that it's hammered by a lot of opponents and it needs to run a +Spd nature to outspeed Adamant Heracross, who murders it with Megahorn.
Mesprit @ Choice Specs
Nature: Timid (+Spd -Atk)
EVs: 4 HP / 252 Spd / 252 SAtk
Trait: Levitate
-Psychic
-Thunderbolt
-Ice Beam
-Grass Knot
Sturdy CSpecs user.
Mesprit @ Leftovers
Nature: Bold (+Def -Atk)
EVs: 196 HP / 172 Def / 32 Spd / 108 SAtk
Trait: Levitate
-Reflect / Light Screen
-Psychic
-Grass Knot
-U-Turn
Barrier passer. U-Turn to scout for CB Pursuiters.
In general, I have no idea what a good Mesprit would be, nor do I know which natures are good for it. Bold seems like a good idea, but then Cresselia does walling and anti-Garchomp / Gyarados / etc. better. It's a conundrum.
