Aerodactyl - Extremely frail, and can be killed very easily
Azelf - Varies when facing certain pokemon
Roserade - Sleep powder not always reliable
Infernape - Got nothing, but I will find some sort of flaw with it xD
Aerodactle*faster*- Taunt+2earthquakes
Infernape*faster*- Fakeout+Closecombat
Azelf*faster*- Taunt + 2psychic
Roserade-*faster*-Sleep-powder + leafstorm
Any faster lead with taunt/fake-out gets you gurenteed,
Any slow lead with lum-berry & a Priority move ko's you.
