Alright, this has been scampered around so much that I'm going to make a very strong push this time. I believe that Exeggutor really deserves an OU analysis. It is the strongest Chlorophyll user with its base stat of 125 SpA (25% stronger than SpA Venusaur and Atk Sawsbuck). Leaf Storm is absolutely preposterous STAB with Psychic, Psyshock, Energy Ball, Sludge Bomb, and Hidden Power Fire waiting in the wings. At 418 Speed (252 neutral nature) under sunlight, it's perfectly capable of messing up opponents with Sleep Powder or hitting them hard with its viable movepool.
Under the sun, Exeggutor can also fill the unique role of being the designated status absorber with Harvest. It can be surprisingly defensive with some key resistances and access to no-sleep Rest, thanks to infinite Lum Berry under sun. If you're game to running some trickier Berry-moves (resist one weakness or infinite pinch berry), Exeggutor does just fine with Leech Seed, Synthesis, and Moonlight for recovering health. It can also provide team support with Toxic, Trick Room, Stun Spore, and Block.
With resistances to Grass, Electric, Water, Ground, and Fighting types, Exeggutor doesn't face problems switching in. These key resistances allow Exeggutor to function decently outside of sunlight if need be, making it unique to other Chlorophyll abusers. It's a fantastic counter to Conkeldurr, Breloom, Gliscor, and even Ferrothorn to some degree. Check out
this post I wrote up a few pages back. I gave a big ol' run through at how Exeggutor can handle common threats.
Exeggutor has been brought up
numerous times with very little criticism or opposition for receiving an OU Analysis. I hope the moderators can see that Exeggutor is a huge threat under sun, a viable Pokemon without it, and a strong promoter of STAB Leaf Storm, Psychic, and team support. I would be absolutely honored to write up an OU Exeggutor analysis if these points are seen favorably. Thanks for your time.
