exeggutor also has blissey, skarmory, zapdos, celebi, salamence, etc to worry about in adv ou, and unfortunately it can't cover all of them. the moveslot that sunny day eats up on the chlorophyll sweeper ends up being pretty significant. any support set is rather inferior to celebi (although it can pass wishes i guess...). it is interesting but still not very good in adv ubers.
