Yeah, I'll be using Eggy, probably Magmar too, since I've already played plenty with Eggy. I'll post a little about my past experiences later.
edit: in. reading is hard .-.
edit 2: Hopefully I can actually contribute now!
I've been running Exeggutor since my very first team in BW NU, back in Stage 0, and I still remember it best for the time my opponent rage-quit when Specs Leaf Storm OHKOed his Swellow. I've run every variation of every set that Eggy has been known to use (bar SubSeed, mainly because I can't play defensively at all in this tier ;-;), and I've yet to regret it. Exeggutor is a juggernaut, offensively and defensively, and it makes me sad that more people don't use him. Plus, the metagame is so open to him right now. With Skuntank usage steadily decreasing, Offensive Exeggutor sets has much less real need to play as conservatively, as Absol (the only other good Pursuit user) has no business switching into Eggy at all. Between Sleep Powder and his dual STAB's, Regen cores basically can't touch him without having to predict around his attacks, switching around like mad to get any footing. Sure Fighting-types have gained Ice Punch throughout BW changes, but it means very little when you still have a 75% safe switch to Sawk and flat-out beat Gurdurr regardless, so claiming he isn't a good Psychic-type in this metagame is tripe. To summarize this all up, Exeggutor is, and always has been, one of the best 'mons in NU, and hopefully the RW will enlighten people of that.
