Vanilluxe: Weather Ball (Gliscor) x3
1. At start of step, if Gliscor is to use U-Turn in a combination, then use Protect (Self).
2. At start of step, if Gliscor is to use Thunder Fang in a combination, then use Protect (Self).
3. At start of step, if Gliscor is to use Swords Dance in a combination, then use Protect (Self). [Let's not fall for that one again.]
4. At start of turn, if Snow is absent, then use Ice Beam (Gliscor).
