I know I've been talking about Ninjask lot lately, but Ninjask can beat Exeggutor even in the sun with X-Scissor. You don't even need full speed EVs or a Jolly nature, just use Protect on the first turn and proceed to gain a boost. If you think they'll switch out, just go for U-turn. It'll either OHKO Exeggutor anyway or let you steal momentum with a free switch.It's also one of the defining forces of Sun Offense teams (which is worth noting since the weather lessens the team's issue with Jynx), since it's capable of setting up Sunny Day and sweeping through most teams with Charizard with relative ease (and can even work as a standalone sweeper), has Sleep Powder still, and outpaces everything barring Choice Scarf Primeape.
On another subject, I've noticed Zangoose is a bit less effective these days. Swellow does the exact same thing while having access to U-turn. In addition, with the rise of Swellow, Zangoose actually has trouble beating it one-on-one. Primeape outruns it and can OHKO with Close Combat. I've been testing its viability for a team slot with Swellow, and in the end I've always found Swellow to be the more useful.
