I dont think everyone understands why I suggested hydriegon. Hydriegon would be such a viable deffoger because it has no fear of bisharp and deosharp/aegi cores and would nerf that playstyle, by far the most common in OU. Hydriegon would have longevity with roost, great utility with defog and superpower for bisharp and dark pulse to destroy aegi and deo d. The fact that a theorymon project pokemon can nerf the most powerful and common playstyle in OU should definately be given more thought. The best set would be:
- 32 speed ev's to outspeed adamant bisharp
- 248 hp for odd hp number and bulk
- 120 defence to only get 30hko'd by a +2 life orb bisharp sucher punch
- attack nature but enough ttack ev's to guarentee a ko on bisharp with superpower (little ev's are needed)
- rest into sp.attack for powerful dark pulses
- leftovers for recovery
- moveset roost/superpower/defog/dark pulse
