I'd like to give this a whirl...
1. Raichu's only choice is to attack Sneasel. And it uses Volt Tackle.
2. Quagsire uses Earthquake, hitting everyone in the battlefield. And Raichu faints, because it's a Ground-type move, and Eletric-types fall in the hands of one.
3. Abomasnow's the only one in the first trainer's team...and so, it struggles to keep moving on...and is beaten by Sneasel. The second trainer wins.
My turn to post a team!
1. Electivire and Magmortar
2. Simisage and Simisear
