I've tried Reflect Chansey before, and it's not too good. A combination of Counter and T-Wave cripples normals with Ice Beams to fend off Golem / Rhydon. Also, a tankish Exeggutor without a single status looks pretty useless on paper. I think two is a good number of paralyzers for a team, especially useful for a team with Rhydon and a non T-Waving Tobybro. Have atleast Stun Spore on Exeggutor.

Your team doesn't seem to have problems with Grounds, and since Exeggutor is always troublesome, go with SToss on Gengar to hit not only Grounds but Exeggutor for neutral damage.

Yea, Starmie and Chansey gives problems to Tobybro, so keep Gengar alive to Tbolt Star and keep Leech Seed on Eggy I guess. Your team is also slow, and may fall prey to Wrappers, another incentive for keeping your Gengar healthy. You want SToss Gar so it wouldn't be stuck with Eggy and force to explode. Other than that, great defenses for normals and specials.
