I was looking for a solid lead that could rapid spin AND set up stealth rock (sorry Starmie) while not being complete fodder (sorry Forry). I found Donphan.
Donphan@Focus Sash
Adamant
80 HP/252 Atk/176 Spe
-Stealth Rock
-Rapid Spin
-Ice shard
-Assurance/Earthquake/Seed Bomb
Moves are self explanatory, except seed bomb can 2HKO swampert 100% of the time. Ice shard deals with Aerodactyl, Assurance with azelf. Focus sash allows you to tank out strong dracometeors, hydro pumps, leaf storms, and either set up or attack back.
Assurance + Ice Shard Takes down Azelf
Seed Bomb 2HKOs Swampert
Ice Shard does 43-51% to Aerodactyl (two ice shards + Rapid spin can KO)
Earthquake does max 87% to metagross/ground weak lead, switching out to a ghost to take the explosion
The point is to set up stealth rock and get back later and rapid spin for there is limited space for rapid spin on an offensive team that already uses or has no room for starmie.
The speed evs outpace 8 spe metagross, swampert, hippowdon, bronzong, ect.
This is all theory, what do you think?
Ok, I tried it out. If it carries the right moves, it can take out the appropriate lead, but suffers from moveslot syndrome.
