Lets turn up the heat guys! I want both of you to use Double Team, make it hard to hit us. Ruby, after that use Overheat, make them uncomfortable. Finally, use Eruption, both of your attacks should do extra well with sunny day still in effect(or at least it should be?)! Snappy, keep your grassy attacks up with a Giga Drain and Solar Beam at Driller! Both should be effective with sunny day .

Ruby: Double Team - Over Heat - Eruption

Snappy: Double Team - Giga Drain @ Driller - Solar Beam @ Driller

notes: sunny day should still be in effect... Jolt, I know you forgot to write it in... Sunny Day always lasts for acouple of rounds... you also fergot to write in ruby's species XD.
