So, originally this was gonna be a Banded Scream Tail with a Brave Nature and 16 IVs in Special Defense. Unfortunately, I
had to do it that way so that I could force Protosynthesis to boost Scream Tail's garbage-ass 65 Attack stat. Even then it'd still need the Band to 2HKO Glowking with Crunch, although it could OHKO instead with Tera-Dark
if the Sun was up at the time... and it still had its Band. The real problem I had with Scream Tail was this; sure, it could lure Glowking in, but it was sacrificing its ability to do literally
anything else to the meta. And that was just sad :/
...
In the end, I made the executive decision to switch to Grafaiai instead. It can't really hurt Glowking with its standard loadout and it gets absolutely destroyed by Future Sight, so it's just as effective a Glowking lure if anything. Furthermore, it does an even better job at crippling Glowking through transferring a Band to it like I wanted to do with Scream Tail. True, Grafaiai can't support the rest of the team quite as well as it's normally capable of (this is true with the Band it starts off with as well as with the Assault Vest it'd get in return), but in my mind, that is
absolutely worth laughing at the face of a Glowking that has to choose what one attack to lock itself into. And, since it can't use the Band due to its attacks being special attacks, Glowking gets locked in quite literally for free.
Grafaiai could also just use the Band itself if you want it to. Knock Off 2HKOs Glowking from full regardless of whether or not it had an item the first time, and Tera-Poison Gunk Shot has a strong chance for a 2HKO as well, despite it hitting against a resistance.
252 Atk Choice Band Tera Poison Grafaiai Knock Off vs. 252 HP / 16 Def Slowking-Galar: 204-240 (51.7 - 60.9%) -- guaranteed 2HKO
252 Atk Choice Band Tera Poison Grafaiai Gunk Shot vs. 252 HP / 16 Def Slowking-Galar: 187-220 (47.4 - 55.8%) -- 78.5% chance to 2HKO
You could run Adamant to guarantee the 2HKO, but there are a lot of mons out there that Grafaiai would not appreciate outspeeding it. Adamant Meowscarada is just one example, but there's also Jolly Urshifu, Modest Greninja, Timid Enamorus and many more.
U-Turn and Parting Shot both allow Grafaiai to get another wall in to take a hit for it, keeping it alive for later. Parting Shot is slashed to the side however as, unlike U-Turn, it gets completely shut down as an option once Grafaiai trades its Band off for the Assault Vest. What you could do is pair this Banded Grafaiai with a Magic Room user. This would disable all items' effects for 5 turns starting from the one Magic Room is clicked, giving you time to get Grafaiai back in to trade the Assault Vest off, and hopefully cripple another support mon when Magic Room wears off.
