Articuno looks promising as a "surprise here's more math for you opponent" piece a la Tapu Koko-GX, but the lack of a good GX attack may hurt it. Salamence over here is like the A. Ninetales to Dragonite's Lapras, which I find really good, and Wishiwashi is becoming playable. Oh my word this set is gonna make the sky fall.
Wishiwashi still isn't "playable", it's "Slightly more viable than just being a stall deck".
Tbh, The Baby Wishiwashi doesn't make Daddy Washi GX that much better really. 5 Energy for one attack regardless of Water support is still too hefty.
