>>43230168Clefable, Corviknight, Mandibuzz, and Rotom-H run SpDef.
Kyurem and Hydriegon are the two strongest breakers in general and both are special. Not much can take hits from a +2 Gengar with it's coverage and Spelltag Hex Dragapult shits out ridiculous damage once stuff is burned/parad. Togekiss 6-0s every fat balance without unaware clef as does Rotom-H.
Physical breakers are way more cucked imo.
Bisharp, Terrakion, and Conkeldurr are the only truly good ones. Zeroara can't really break without bulk up but it gets walled by either Seismitoad or Kommo-O because it has to drop grass knot or play rough.
