Oh, i get it. Random teams as well. Great. Totally random pokemon, EV's, IV's, nature, everything. Great. Just throw us all in the deep end and see who has a Water Pokemon, then (I pity the loser that gets Psyduck!).
Wynaut with CounterCoat (or heck, just one of them will do) at Lv. 100 would be able to take many attacks from the so-called Ubers, and reflect it right back at them.
I'm surprised you got a Latias, Zapdos and Wynaut all on the same team, though. Latias is Hoenn, Zappy hails from Kanto, and Wynaut iirc is Johto (or, even just Latias and Zapdos, if that Wynaut was just for example purposes). How does this thing work again? You say 5 battles for each generation. Is that measured in pokemon games (hence, FR/LG + R/S/E = Latias + Zapdos)?
Anyways, i'm quite happy to sit out on this one. While i have faith in my knowledge of most pokemon, having Snore on a pokemon that doesn't have a bloody self-sleep move is stupid and far too situational. Also, Sunny Day and Sandstorm on one pokemon? You got the short straw, it looks like.
That random pokemon is what really bugs me. There's little to no strategy when you've got a random mix of 6 pokemon from a possible group of 1xx pokemon. To get any synergy is lucky, to have any pokemon that's even halfway viable is like when hell freezes over. If you guys really need one last person to fill the last spot, then fine, contact me. But i'll safely sit out of this one for the time being. It's not really in the spirit of a 'Scramble' challenge, in my opinion. It's just pokemon lottery.
I'd battle you, but i don't use netbattle.
