Ambipom

While most priority users do outclass it, Ambipom has a few tricks that make it perfectly viable in DW, namely its Technician ability and its huge movepool. Technician is a godsend for Ambipom, whose array of weak moves receive a power boost. Fake Out, one of Ambipom's most commonly used moves, now has an enormous 90 Base Power instead of 40 after taking into account the STAB and Technician boosts. Fake Out also has +3 priority, making it one of the fastest moves. Furthermore, Ambipom has an adequate base 100 Attack stat and a superb base 115 Speed. Despite its lackluster Normal typing, Ambipom also gets access to uncommon and useful moves in U-turn, Pursuit, Low Kick, and Low Sweep.

On the other hand, Ambipom's stats, typing, and overall utility is disappointing. Its excellent Attack and Speed stats are let down by its base 60 Special Attack stat, which makes going mixed unfeasible. Ambipom also has horrible 75 / 66 / 66 defenses, making tanking most any attack difficult. In addition, Ambipom's bland Normal typing gives it a lack of resistances and STAB coverage that leaves much to be desired. As a priority user, Ambipom is greatly outclassed by the likes of Scizor, Dragonite, Lucario, and Breloom, all of whom have better priority moves, typing, or stats. On top of that, Ambipom has few viable options, making it extremely predictable. All in all, while Ambipom is outclassed by many Pokemon, its unique qualities do give it a niche.
