I saw this article posted on the official Pokémon Organized Play website (soon to be Play! Pokémon) and they actually have some decent lists posted from Nationals participants, all of whom apparently made at least top 32.
I suspect the one list is Con Le’s Sablelock as it has Honchkrow SV tech… I don’t think anybody else played that, so it’s likely that this is what he used:
|Pokémon – 29||
T/S/S – 19
4 Cyrus’s Conspiracy
|Energy – 12|
My apologies if it isn’t his list, but it looks pretty solid regardless.
(Also sorry if this is old news, I just noticed it on the site yesterday.)
There were also Gardevoir and Steelix Prime lists shown, which I’ll repost here too (for your convenience).
Pokémon – 29
4 Ralts PL
|T/S/S – 19||Energy – 12|
|Pokémon – 20||T/S/S – 27||Energy – 13|
