Slowbro can be PP stalled IF you got a team of unparalyzed Chansey/Starmie SOME of the time vs. the Psychic set, but paralyzing Chansey has never been difficult and Starmie is absolutely not seen on all teams (and some times when it is, it takes sleep). That's it.
Just because you don't get a 100% guaranteed auto-win in all of the possible scenarios and outcomes does NOT mean that getting an invulnerable Pokémon isn't broken.
And then you imagine the cases where you end up versus BOTH a paralyzed Dig Rhydon and Dig Slowbro...
I can't believe that I have to explain why having invulnerable Pokémon is a broken and bad thing. Seriously?
