You're on.
Arena: The desert..! Yeah, that's it. I'll write some fancy text later, but that's going to be my new arena. There is one big rock pillar in the middle, more like an obelisk. There's a four turn Sandstorm, then two turns without. So wheatermoves are only usable in the two turns that it's off, as soon as the two turns are over, the sandstorm is back. Also, Earthquake is pretty ineffective, due to all the sand. Dunno what other moves, but just think logically (ref).
DQ: 7 days.
Number of pokemon: 3
I send out first, you attack first.
