For this 'Cold Front Apeal' River and I will both send out our female Sneasels. River's is named Darkwind while mine goes by Hailee.

To start off Darkwind will freeze a patch of ground with Ice Beam while Hailee starts a short Hailstorm. Then Darkwind will use Swords Dance on the frozen ground. She should start spining fast enough to start sucking up the Hail into the vortex. After Darkwind has started to spin Hailee will shoot a weak Blizzard into the the forming twister. Once there is a white tornado surrounding Darkwind, both Sneasels will use Sunny Day so that it gets super bright and all of the ice will gliter in the light.
