>>25003929Depending on the rules you're using, Sleep can be restricted so it only affects one Pokemon at a time. Pokemon like Breloom and Amoongus who have 100% accurate Spore tend to be its main users.
Flinch is generally considered a bonus, except for Jirachi's Iron Head and Togekiss' Air Slash.
Confusion is too unreliable if you're not using Swagger + Foul Play, and some rulesets don't let you use that combination. Again, it's useful as a side-effect, like on Machamp's DynamicPunch.
