I'm guessing...
Snivy vs Servine
~ Ash goes for the thing he did in the past, and Snivy tries attract.
~ Trip's Servine uses Safeguard. Then uses Attract on Snivy.
~ Ash figures he better switch to a male. Sends out Tepig.
Tepig vs Servine
~ Servine tries Attract, it fails so he switches.
Tepig vs Timburr
~ Ash keeps Tepig out, uses Ember, Timburr's block thing covers him from Ember, so he tries Tackle and Nitro Charge.
~ Timburr uses Bulk Up and Low Kick, hurts Tepig. Ash recalls. Timburr Bulks Up again.
Tranquill vs Timburr
~ Timburr Bulks Up again, Ash tries a Quick Attack, it fails. Timburr then uses Rock Throw, and hits Tranquill.
~ Tranquill uses Air Cutter and gets a critical hit on Timburr, Timburr gets OHKO'd. Its revealed to Ash and Trip, that Ash's Tranquill also has Super Luck instead of Big Pecks.
~ Trip sends out Vanillite.
~ Safeguard ends.
Tranquill vs Vanillite
~ Vanillite uses Hail, right off the back, and Tranquill hits it with a Quick Attack. (No crit), Tranquill gets pummeled by hail and gets Ko'd, while Vanillite's Ice Body heals some damage done by QA.
Tepig vs Vanillite
~ Hail is still going.
~ Tepig's Ember fails, and Vannilite uses Icy Wind which slows down Tepig.
~ After getting hit by a few Icy Winds, Tepig has trouble using Nitro Charge, and as a finisher, Vanillite uses Water Pulse and Tepig gets Ko'd.
Snivy vs Vanillite
~ Hail ends, Vanillite uses Icy Wind and it misses.
~ Snivy finishes it off with Vine Whip. Snivy takes no damage in this fight.
Snivy vs Servine
Back where they started.
~ Ash lies and tells Snivy that Attract will be useless. Trip's guard goes down and doesn't use Attract.
~ Then while battling, they both order Attract at teh same time, and both pokemon get attracted to each other.
~ Then they bre...each try to call their pokemon out of it. Snivy lands a Leaf Blade, and Leaf Storm. Servine only lands a Cut. Then they call Cut and Leaf Blade again and both infatuated pokemon KO each other. It ends in a draw.
