I approve of Crobat, one of my favorite lines when I can be fussed to evolve one, but I'm curious you included Lunala!Necrozma. I haven't kept a legendary around other than for looks since Gen IV. And that reminds me that I'm still upset that they failed to add a real hall of fame between games. That was one of my only real hopes for USUM and if they don't improve that going forward on the Switch, I am never getting over my salt. Litten was my Sun choice and boy was I disappointed in the final form. Picked Rowlett for Moon but I never got around to finishing it. So naturally I had to round out the Alolan trio with Poplio this time and lemme tell you, that fairy typing is quite helpful when I'm not grimacing at poison types landing the first blow. Its more annoying to run into other fairy's since I don't have a hard counter, Chesnaught can learn one of the poison tm's I found but it lacks the special to make it viable, and none of my team can learn steel moves so eh. I've been sleeping on Crabominable for a while now. He had some use against Kahili but by and large Primarina's ice beam settled any flying types.
