[Other Options]

<p>Hydreigon has the defenses to run a bulky support set consisting of Thunder Wave, Dragon Tail, Taunt, and Substitute with a defensive EV spread, but it would be a waste of its offensive potential. Moreover, such a set would face severe competition from MultiScale Dragonite, who has better defensive stats and access to Roost. However, such a set would work well with entry hazard support.</p>

<p>Charge Beam is an option to boost Hydreigon's Special Attack and attempt a sweep, but its inaccuracy can cause issues. Moreover, the SpA boost is not a guaranteed one. Hydreigon also has a usable base 105 Attack, along with a physical movepool consisting of Crunch, Outrage, Earthquake, and Head Smash. It can put these physical options to great effect by surprising its normal counters and running a mixed set.
