Jigglypuff

Jigglypuff is great Steel Beam fodder that can Perish Pass if the opponent has no Steel Beam users. Naive Jigglypuff is already OHKOed by Varoom Steel Beam. Since Jigglypuff is very slow, Taunt and Encore are among its best disruptive options since they still work if the opponent has a Substitute up. Alternately, Jigglypuff can use Knock Off if you anticipate opponents trying to hastily Taunt it off Perish Passing. Jigglypuff can also try to be a covert Stealth Rock user, although its very slow speed will hinder its ability to do much. Jigglypuff can also try its luck healing opponents and cutting its own health with Pain Split. Tera Dark lets Jigglypuff ignore Pranksters, while Tera Ghost lets it escape trappers more easily.
