Beeheeyem is SUCH an underrated threat in NU. Yes, Swoobat is interesting, but Beeheeyem's awesome 125 special attack is somehow overlooked. Honestly, with its low speed, you can give it synchronize and watch it Trick Room sweep. You could make it more bulky and set up some Calm Minds, or maybe you prefer Nasty Plot. The absolute best set there is though, is Analytic (0 speed IV, Quiet Nature) Choice Specs Beeheeyem. It has many coverage options and wit hthe boost from analytic combined with some investment in bulk, Beeheeyem is sooo powerful.
Swoobat aint got crap on him
