That topic lost me already when author wrote that you now have a worse matchup against Wigglytuff. Yeah cause everyone was using double resisted Shadow Balls against Wiggly and now will use double resisted Shadow Bones
Don’t look at the theories. Here is what you need to know and what you need to do:
Think of the role your A-Wak needs. If this is just a general performance, then you compare A-Wak Shadow Bone and A-Wak Shadow Ball on PvPoke. For most reliable data you don’t put a second move because then PvPoke will take into account that opponent takes the Bone Club baits, while in practice, people might not and thus what seems to be a winning matchup is actually a losing matchup.
If however you need specific pokemon to beat more consistently with your A-Wak then you should compare per opponent which moveset is better. Don’t involve Bone Club with it, except if you want to know whether a matchup is bait dependant or not. Because in practice you will find that people have big balls and won’t take baits and what should be a winning matchup in theory will be a losing matchup in practice
In my opinion, Shadow Bone is an upgrade, but not as much as you’d think. It feels very underwhelming against Azumarills, however you get to your big hitting move faster than usual. And this can be an absolute gamechanger. The defense drop might turn some opponents into easy farms, whereas you usually might need that Bone Club to kill and prevent them from using a move
