is hydreigon rare
Giving Hydreigon a Choice Scarf makes it capable of revenge killing faster threats, which is an obvious use it has over the Choice Specs set. On the other hand, Choice Scarf Hydreigon is completely inferior at actually KOing opponents, and it's useless in the face of sturdy Pokemon.verview. Hydreigon belongs to the special group of Pokemon that can boast they possess no true counters: they potentially carry a move that can OHKO or 2HKO any Pokemon in the game, and as such are virtually impossible to switch into. Its peers include such wrecking balls as Deoxys-A, Excadrill, and Salamence.
