I finished 1726 with 24-6 and 12th/1209 place in the world, but I'm in Junior Division so it's not impressive -w-
I ended up getting matched up with way too many low-ranking players, so I didn't get very many high-quality battles. I didn't really see that many of the Top 12 Pokemon either, probably because I didn't play many high-rankers. Gardevoir was much more common in my battles, and I don't even remember facing any Charizard.
I ended up not using quite a few things on my team. Jellicent's Mental Herb was nearly untouched. U-turn and Will-O was on my Talonflame, too (what else am I supposed to have?). I do have to admit that Abomasnow's Ice Shard helped me once to secure a speed-tie in a 1v1 against M-Camerupt though.
Overall, I'm kind of disappointed in my performance (lost against nearly half of my matches versus Japanese players, and most of my wins were because the opponent was dumb), but even so, I claimed a rather high spot in the rankings. And I ended up winning against everyone I faced that wasn't Japanese or Korean. So my battling had to be at least decent. And my win-loss ratio was a pretty good step up from my last competition.
P.S. There's this certain amount of extreme "GOTCHA!" when I see Smeargle on their team, lead in the middle with Jellicent, and I Protect on everyone and Jellicent Magic Coats. However, one time, Smeargle Spiky Shielded on the first turn, and I Magic Coated into nothing. Oddly, he then Dark Voided the next turn, even though he knew I had Magic Coat.
His entire side fell asleep. I don't know whether he knew what he was doing or not.
