Seismitoad UNR->C: how is the toad unranked? the greatest switch to rotom-wash that gets up rocks pretty much, which might not sound that big when ferro exists but the fact that rotom is as good as it is is the fact that it invites every threat with volt switch, seismitoad at worse at least forces a hard switch, good utility between knock, toxic and the potential burns and naturally great typing dealing with threats like heatran, zapdos, mag, slowbro, rotom-h, gengar (check), gren (no hp grass, check), rd manaphy. Spdef is the only set imo (sassy), cause mons like bish and drill, which seismitoad on paper should check it, seem to always manage to overwhelm it. Its definitely not an easy mon to fit in any team and fundamentals such as lack of reliable recovery (tho i think rest is a potential niche option) and pokemon like gastro, which cover most things seismitoad does, existing. Its honestly a great pick on presure stall teams that follow the typical suicune/zapdos/clef line since those tend to be a bit pressured by momentum from rotom into wallbreakers.
Might post more if i fell like it, we'll see
