Unfezant

Unfezant may seem good on paper, boasting a solid Attack stat, decent Speed, and Super Luck, but that's where the positives end. Unfezant's lack of a good movepool makes it outclassed terribly by other Flying- and Normal-types like Dodrio and Kangaskhan, since they actually get access to strong STAB moves whereas Unfezant is stuck with worse options, especially 60-Base Power Flying moves like Pluck and Aerial Ace. Unfezant's Speed tier is good, but it is still outsped by common Choice Scarf users and offensive Pokemon such as Primeape and Lycanroc, which can easily dispose of it. Finally, Unfezant is often forced to run a support set that relies on the 60% Hypnosis due to its limited movepool. It's very unreliable in the metagame because of this and has no reason to be used over good offensive Flying-types such as Dodrio and Oricorio-G that possess a better matchup against bulky Rock- and Steel-type Pokemon like Regirock and Aggron.
