I tested this mon slot and it's a very excellent pokemon with a surprisingly versatile movepool and a decent amount of viable sets. It has a very powerful knock off when boosted by choice band, amazing speed tier, and a super solid move in flower trick.
Many might compare it to tealpon who's a tad stronger and faster when teraed. However I definitely think meows has strong niches over her. For example, it has a much stronger knock off and uturn, and a far greater base speed stat, meaning without tera it's going to be better in most situations. Triple axel also let's it very easily destroy most fly mons such as torn, or zap, torn being the better target as you can immediately threaten a knockout on it off rip due to how fast meows is. The dark type is also pretty solid for resisting ghost in a pinch. Finally, it has access to things like Trick to disrupt opponents (on scarf sets and some band sets) and spikes for boots sets. Il
Tldr, meows is very fast and surprisingly strong.

This pokemon is excellent. While its sets are somewhat similar in nature they're all effective nonetheless.
Swords dance is a very threatening breaker that can also function as a great revenge killer with ice shard (and tera). It's also a great knock off user, capable of first knocking, then eventually muscling through checks throughout the course of a game.
+2 252 Atk Tera Ice Weavile Triple Axel (120 BP) (3 hits) vs. 248 HP / 252+ Def Corviknight: 346-412 (86.7 - 103.2%) -- 99.9% chance to OHKO after Stealth Rock
+2 252 Atk Weavile Triple Axel (120 BP) (3 hits) vs. 248 HP / 252+ Def Corviknight: 259-308 (64.9 - 77.1%) -- guaranteed 2HKO after Stealth Rock
It's tera types are also rather versatile as well, with ghost to take bpresses or Dnite espeed, ice for more damage, or fire to absorb moltres burns.
The set that really made me want to make this post, however, is choice band- not much outside of Alo (easy to account for with the right teammates) or the rare toxapex wants to take this thing on.
For example, heres an example of how strong this is:
252 Atk Choice Band Weavile Triple Axel (120 BP) (3 hits) vs. 248 HP / 252+ Def Corviknight: 196-233 (49.1 - 58.3%) -- 99.9% chance to 2HKO
I recently laddered up to 1810 with band Weavile + hatt & kingambit, and with the right plays, it's very easy to keep rocks off the field for most of the game.
Tldr: I think it's frailty and rock weakness of the mon is easily worth considering it's damage output, unique and strong stab type, and amazing speed tier.
