>>15027891It's a legit "bind" move, so yes it does. It will kill any pokemon paired with toxic in 4 turns without further attacks. It's a viable method, but falls flat against steel types.
Yoou can also run gooey goodras and give it an assault vest to gain a 50% defence boost. It will become completely immune to special attacks, incapable of being oneshot by any special attack and gooey will punish all physical attackers.
If you have one single pokemon who has rain dish, swift swim or dry skin, I advice going hydration rest trap with toxic.
If you dont have anything that benefits from rain, get a gooey one with 4 offensive moves for the 50% defence boost.
