I'm not going to answer all of these, but I genuinely think that Sub Bulk Up is easily Corviknight's best set. Sure, it doesn't offer the sheer utility that the defensive set does, but it's still an incredibly potent set that surprisingly few teams are equipped to deal with. Its' effectiveness vs. fat teams is especially useful in a team where balance and bulky offense are the best playstyles, especially since it can use Pokemon like Ferrothorn, Toxapex, and even Tauntless Corviknight as setup bait.Queenly Majesty blocks priority in singles as well. You're right in that it does not get Knock Off, but Queenly Majesty is the preferred ability as it grants Tsareena immunity to priority attacks and Prankster.
I got a little bored and felt like creating some questions for discussion that you all can answer to your heart's content:
1. What do you believe are the best sets for the following mons?
2. How do you feel about these mons? Are they good, not that great, underrated, or overrated?
3. These mons seem to have fallen off a bit in the post-dynamax metagame. What do you think?
That's all from me for now. Merry Christmas, happy holidays, and I sincerely hope you all have a wonderful time.
It also pairs with those two exceedingly well, helping to beat/stall out Pokemon like Hatterene and Reuniclus that give those two trouble, and creating an excellent defensive core that's incredibly splashable, Granted, I haven't tested the other sets nearly as much as I've tested Sub Bulk Up, but it just has so much going for it in this metagame that I'm inclined to regard it as Corviknight's best set. Though that being said, it isn't AS good as it was in Dynamic meta
