Well Crocune is honestly a total beast. It's quite underestimated for some reason but it can really beat up whatever it wants. Raikou isn't popular anymore and even failvire is starting to decline a little. Jolteon is almost never used and Zapdos is kind of in the middle of the pack in usage these days. A lot of its counters have declines in usage so you can abuse that. Hell you can even stall out some Vaporeon, and Milotic is rarely seen so you probably won't have to worry about that. I love Suicune.
