Not just any tank. I want it to have either "shell armor" or "battle armor" as it's ability, for crit immunity. Closest I could get is pic related.

It's got:
>immunity to toxic
>snarl for special attackers
>good overall stats
>wide movepool, including support
>great defensive typing

what it lacks:
>defense boosting moves outside acupressure and double team
>healing outside of rest
>a way to prevent forced switching

Does /vp/ think there's potential here, or should I pick a different mon? Maybe something with lucky chant?
