Thanks for appreciating my rate^^ The team looks good now, here are my observations:
Exeggutor: looks good, you don't need Mega Drain anyway since you have Stun Spore for Starmie, Psychic for Golem/Rhydon, and you won't recover a lot anyway
Snorlax: consider Hyper Beam over Surf (dunno how much Earthquake deals to Golem/Rhydon, but your team should have no trouble with them to begin with), otherwise looks good. Hell, considering that in gen I Hyper Beam deals more damage than Selfdestruct, you could even replace the latter with the former, unless you're paranoid of the possible recharge turn.
Golem: looks perfect (don't hear the people who prefer Rhydon, Explosion is just too good^^)
Starmie: again, good choice. I generally prefer him to Alakazam for the superior physical defense and the more varied offense. A good Para user too, if that's the route you're taking (which you should since you use Tauros)
Chansey: well, I recommended it, so who am I to disapprove?^^ On a more serious note, I disagree on swapping IB with Blizzard. The power gain is not exceptional and, most importantly, not needed on Chansey. If you predict Tauros switching in, you should Thunder Wave him anyway - once it's paralyzed, whether you hit him with Ice Beam or Blizzard means little. Conversely, using Ice Beam gives you better chances against stall wars with opposing Alakazam and Chansey. Moreover, since Chansey switches in a lot, it's easy to deplete the PPs of Blizzard on wrong predictions and whatnot. Once Chansey finishes Blizzard/Ice Beam PPs, it's a completely free Golem/Rhydon switch in, and you don't want that. Stick with Ice Beam.
Tauros: looks good.
Last thing, I agree with Crystal on the fact that Chansey is better than Alakazam on this team. The things you'll need to switch Chansey/(Alakazam) into generally pack Thunderwave (Alakazam and Starmie come to mind), and only Chansey can function even if paralyzed (just remember that, if that is the case, Golem/Rhydon outspeed you)
