My favourite second favourite Pokemon in UU!
Ambipom (M) @ Toxic Orb
EVs: 176 Atk, 128 Def, 128 Sp. Def, 76 Spd OR 252 Atk, 252 Spd, 4 HP
Nature: Adamant (+ Atk, -Sp. Atk)
- Fake Out
- Low Sweep
Fake Out is a must-have on this guy, the +3 priority allows it to surpass moves such as Mach Punch as it causes the opponent to flinch, wasting one turn and getting the Toxic Orb working. Since it's base power is 40, Technician increases this to 80, and along with STAB makes it a good first move. Since the Toxic Orb has Poisoned Ambipom, Facade's power becomes extremely high with STAB benefit. Low Sweep is also a very good option to use to clean up Steel or Rock Pokemon who would otherwise wall Ambipom. It is Technician-run giving it a base of 120 power. Fling once again is powered by Technician and Poisons the opponent, making it a better option than Toxic. Since it is Dark, Ghost types hopefully will cop a bit of damage, as they are one of the only things that will stop him. Switcheroo is also an option, giving the opponent a useless Poisoned stat, whist Ambipom benefits from the opponent's item.
As you can see the core of success for this set is Technician. Pretty much the only thing that will stop this guy is a Ghost type, as Fling won't be sweeping it.
