RBY OU Rapidash Gimmick Team

I've been trying to make Rapidash work in OU on Showdown (big order I know), though I'm having a lot less success on the ladder with Dash than I did with other low tiers (Kingler in particular).

This is the team I'm using. I'm wondering if if I could be doing something to better optimize it.

____________

Rapidash (Lead)

-Fire Blast
-Fire Spin
-Agility
-Hyper Beam

Anti-Sleep lead. 2HKOs Exeggutor and Jynx with Fire Blast and outspeeds both of them. Can beat slower Mons like Lapras and Snorlax with Fire Spin luck. Chosen over Moltres since it outspeeds Jynx and doesn't die to BlizzBolt. Can Agility into an unbeatable speed tier and use Fire Spin like Dragonite uses Wrap. Hyper Beam to cleanup after Fire Spin.
____________

Exeggutor

-Sleep Powder
-Stun Spore
-Psychic
-Explosion

Opts for Stun Spore to spread paralysis. The rest is fairly standard.
____________

Chansey

-Ice Beam
-Thunderbolt
-Softboiled
-Thunder Wave

Opts for BoltBeam to deal with Water types that counter Dash.
____________

Golem

-Rock Slide
-Earthquake
-Body Slam
-Explosion

Deals with Jolteon and Zapdos who threaten to paralyze Dash.
____________

Tauros

Body Slam
Hyper Beam
Earthquake
Blizzard

For cleanup.
____________

Starmie

Blizzard
Thunderbolt
Recover
Thunder Wave

Spreads paralysis. Chosen over Alakazam for Thunderbolt.
____________

The idea behind the team is that you spread paralysis with Chansey, Egg, and Starmie, then use Fire Spin/Tauros to cleanup. Any suggestions on how to improve greatly appreciated.
