>>18868084If you run a dedicated rain team, yeah. Even without rain, Toxicroak usually manages to recover a solid chunk of HP and keep big subs up; it's main problem is that it's slow.
Other good substitute abusers are classic subpunchers, Toxic Heal Breloom is a good one. While substitutes did get nerfed, that doesn't make them useless.
Substitute Sucker Punch Bisharp is another.
