Well the point of the Speed for Misdreavus was that Braviary is now capable of setting up on the standard defensive Misdreavus as otherwise it will outspeed and burn you with WoW. For the situation against Rampardos it is assuming that it comes in as Braviary Subs or Bulks Up. At that point Braviary is only really losing to Special Ramp as the physical sets need to hit you with Head Smash or Superpower to break your Sub. Using Head Smash with either set will cause a lot of recoil for Rampardos to the point where Braviary can kill with a +1 Brave Bird ( does 51% minimum) Still I definitely get your point about the 252/240+ spread and Braviary's bulk truly shows how amazing it can really be, with the following calcs being absolutely impressive. I'll make sure to mention your spread on the post!
- 252SpAtk Solar Power Charizard (Neutral) Fire Blast in Sun vs 252HP/240SpDef Leftovers Braviary (+SpDef): 84% - 99% (340 - 402 HP). Guaranteed 2HKO.
- 252SpAtk Life Orb Ludicolo (Neutral) Hydro Pump in Rain vs 252HP/240SpDef Leftovers Braviary (+SpDef): 64% - 75% (261 - 307 HP). Guaranteed 2HKO
