This bypass is known and intentional since it's so terrible. If you do want to keep trying it, though, I suggest Diglett, since it has the lowest defensive stats. Equip an Iron Barb too.
I tend to see it on sand teams with Retaliate as a decent revenge killer and as one of the few extant Sand Rush users. Still an overall pretty niche pick when sand already has zolt to fixate on; they don't particularly synergize with each other.
