Salazzle-GX could prove to be pretty powerful and I could be wrong, but I think a lot of players might get too caught up by the hype of a seemingly-broken attack to realize it's actually just ok. Heat Blast is nice because you hit Shaymin (which will undoubtedly rotate so this doesn't matter) for 110 and you can OHKO Lurantis-GX and Golisopod-GX with it. With a Choice Band, you upgrade to OHKOing Decidueye-GX and Solgaleo-GX. (Who knows how relevant these will be in the next format.) Unfortunately, there isn't much else you're taking Knock Outs with early on in the game for you to really make use of Wicked Claw. In addition, you need to take three Prizes to go 150 + 30 with Choice Band, which may be a bit of a hike if you're forced to swing for only 110 for a while. We'll see what pairs best with this card in the future.
